History YMMV / MarvelAvengersAlliance

** [[Comicbook\RunAways Molly Hayes]] has been met with overwhelming approval from the fanbase, due to her being a BadassAdorable. Several players have even taken note of her abilities, which not only works quite well in tandem with other characters, but can cause a LOT of damage in the process. [[https://www.youtube.com/watch?v=Ejor6G5WF_I Observe.]]

* BrokenBase: The introduction of Venom as a boss in Daimon Hellstrom's Spec Op. While many are simply happy to see him appear, others are unhappy for various reasons. 1) The Venom in-game is Mac Gargan, who is arguably the least popular version. 2) Some players would rather see Mac Gargan in his original role as the Scorpion instead. 3) Venom arguably appears as a supporting nemesis in a story arc he has little historical relation to, whereas some argue that the character is popular and has a strong-enough legacy that he should have been introduced in his own standalone Spec Op. (Though naturally, the developers are pressured to concentrated their efforts on characters Marvel still has the adaptation rights to, meaning much less Fantastic Four and Spider-man content overall.) 4) His introduction as a villain (rather than a hero) means that he will only be recruitable via Lockboxes in the future, a contentious game mechanic. (Eventually, the Flash Thompson version of the character would be made the first to be made available, as a PVP bonus, then recruitable.)

* ArchivePanic: Brand new players start off facing 12 lengthy chapters in Season 1 and 4 in Season 2, each with six missions apiece, and an ever-expanding roster of heroes at daunting price-points. And Season 2's chapters are still in production...

* UnfortunateImplications: The [[TheSneakyGuy Infiltrator]] class is the only female-dominant one in-game, which is problematic because 1) [[FragileSpeedster they tend to focus on evasion and distraction rather than damage output, and cannot take a hit]], which 2) makes them unviable in [=PvP=] due to a focus on quick and heavy unavoidable damage as well as stealthy attacks (which Infiltrators cannot counter, thus making their class advantage significantly less useful), hence 3) making them unpopular amongst certain fans, especially of the sexist variety. This is in contrast with the [[TheSmartGuy Tactician]] class, which is generally seen as the best class. However, it only has 3 females compared to 10 males, many who are also limited edition and hence not readily purchasable for new players. This possibly reinforces stereotypes of TheChick relying on 'sneakiness' and unable to endure much damage, while men are more suited to be TheLeader.
** Subverted because the first (and for a long time, only) female Tactician, Emma Frost, is seen as top tier in both the Tactician class and the game as a whole. The double subversion is she is portrayed as a LovableAlphaBitch, drawing the unfortunate conclusion that she only keeps up with the males by being a dry-witted RichBitch. Of course, with class-mates like Cyclops, Magneto, Red Hulk, Hank Pym, and more, it may just be that Tacticians tend to be jerks in general.
** The game also does pretty well at averting GuysSmashGirlsShoot. Most of the women have at least one melee attack, those who are purely ranged have useful support moves, and impressive Bruiser powerhouses include She-Hulk, X-23, and Valkyrie, while impressive Scrappers include Magik and Sif. On the other side, several men are entirely ranged, but that number includes dangerous powerhouses like Hawkeye, Magneto, and Doctor Strange.
** [=SpecOps=] 9 features Rescue, the second recruitable female Tactician, also time-limited, like Emma. Basically, she's a CombatMedic, playing a supportive role while the other members of her team do most of the dirty work. Most of her abilities are healing and shielding maneuvers. Her only attack can remove nasty counterattack abilities in the enemy, but aside from this, it does minimal damage. Rest assured, she's pretty damn badass despite all of that, but the only thing holding back the niggling StayInTheKitchen vibe is that she makes it clear that this particular moveset is Pepper Potts' own preference.
** Nico Minoru needs to be afflicted with Bleeding to use her magic. BloodMagic, yes, but she's a ''teen goth''. Of course, this is an intentional reference to the very intentional implications of the comic.

** ComicBook/RedSkull in Mission 2-7-5. In the middle of boss fight, there's suddenly an explosion (harmless to your party) and he disappears without any track, leaving his two ComicBook/{{HYDRA}} goons behind.

* EnsembleDarkhorse: Ever since [[http://img4.wikia.nocookie.net/__cb20130723221600/avengersalliance/images/thumb/1/14/Marvel_Avengers_Alliance_Season_2_Teaser.jpg/200px-Marvel_Avengers_Alliance_Season_2_Teaser.jpg his appearance in the teaser for Season 2]] (and possibly because of [[HandicappedBadass his unique status]]), there has been quite a lot of interest in Armless Tiger Man.

* TearJerker: This exchange between Nightcrawler and Mystique in Heroic Battle Season 2 Chapter 1 Mission 3:
-->'''Nightcrawler''': I have seen enough hate, Mother. I will not become hate. Müssen wir immer gegeneinander streiten?[[note]]Must we always fight against each other? [[/note]]\\
'''Mystique''': Ja, mein Sohn. Wir müssen.[[note]]Yes, my son. We must.[[/note]]
** Later once you won:
-->'''Nightcrawler''': Each time I confront my mother, I emerge...ein bisschen müde.[[note]]a bit tired.[[/note]]\\
'''Professor X''': You are forced into a realization, Kurt. It is always better to fight the difficult battle and suffer its aftermath once. The alternative, of course, is to surrender and live with that surrender every day of one's life. That is precisely what your mother has done.\\
'''Nightcrawler''': Ja, aber...diese Kämpfe, die sind schwer.[[note]]Yes, but... these fights that are difficult.[[/note]] She points down a path I will not follow.
** If you lost, on the other hand, Nightcrawler will use his teleportation power to [[ScrewThisImOuttaHere escape]] and completely absent from conversation. Mystique desperately calls for him.
-->'''Mystique''': Come back, my son. Come back. We don't have to fight any more.\\
[''in another place'']\\
'''Nick Fury''': Where is he?\\
'''Professor X''': He's teleporting around faster than you can track him.\\
'''Nick Fury''': Slow him down, Professor. This is his fight in the end, and we have to make sure we help him win it.\\
'''Professor X''': Kurt. You cannot run. We need you to stand and fight.

-->'''Nightcrawler''': Each time I confront my mother, I emerge...ein bisschen müde.[[note]]a bit tired[[/note]]\\

'''Nightcrawler''': Ja, aber...diese Kämpfe, die sind schwer.[[note]]Yes, but... these fights that are difficult [[/note]] She points down a path I will not follow.

Mystique: Ja, mein Sohn. Wir müssen.[[note]]Yes, my son. We must.[[/note]]

-->'''Nightcrawler''': Each time I confront my mother, I emerge...ein bisschen müde.[note]a bit tired[[/note]]\\

* GoodBadBugs: In an attempt to balance out PvP, Playdom introduced a Level Cap system in September 2014's Beta Tournament, which put everyone at a certain level. Unfortunately, while this was supposed to apply to the weapons as well, those that were 'Custom' were unaffected, doing the exact same damage they were before, resulting in a ''lot'' of [[ThereIsNoKillLikeOverkill hilarious]] one-hit-kills by Agents. However, this ''does'' have the side effect of making PvP progress for some players a lot easier and less frustrating to go through, while others......[[GameBreaker aren't]] [[ItsEasySoItSucks as amused.]]

** Leveling up your heroes ''will'' be a chore, since the upper levels award extra boosts for PVP stats. Hero Level 11 will take 24 hours to level-up your heroes ''one at a time'' with 80 heroes and counting. Since Levels 13 and 14 take almost 2 days to complete, gameplay is essentially extended by ''one year'' just to max out as many of your team.

** Mystics/Elders/Mentalists (they're the same mook with different stats) from Spec Ops 21. They're essentially improved versions of Emma Frost, but what made them so horrible is the fact that they can preemptively apply Mental Anguish to an attacking hero, meaning that said hero will lose about 50% of his/her HP after attacking. If you're facing more than one in a fight, you ''will'' lose at least one of your heroes in a couple turns.

*** The rewards for Incursion, while not involving a roulette, is just as infuriating, especially with the high chance of getting an outmoded [=PvP=] armory item or [=PvP=] challenge tokens over a relatively small chance to get the weapon instead[[note]] With the former, the issues are that the bonuses are simply dwarfed in comparison with newer armory bonus items, as well as selling for a mere 30 Silver each. As for the latter, they're relatively useless outside of [=PvP=], and even worse, you can't sell them whatsoever.[[/note]]

*** The rewards for Incursion, while not involving a roulette, is just as infuriating, especially with the high chance of getting an outmoded [=PvP=] armory item or [PvP] challenge tokens over a relatively small chance to get the weapon instead.

* BadassDecay: Characters who might be reasonably expected to be overpowered, such as Wolverine, Deadpool, and Squirrel Girl, are judged to be fair to middling performers. However, with the right combination of weapons/characters/Iso-8 gems, they can more than hold their own.

** FridgeBrilliance kicked in when Eddie Brock became playable...as Anti-Venom. His bio still credits him as the original host of the Venom symbiote.
* CharacterTiers: Some heroes are definitely stronger than others, especially in [=PvP=]. The topmost tier (heroes who show up frequently if the player has them) is usually Captain America, Rescue, Phoenix, Thane, Emma Frost, Human Torch, Mockingbird, Brown-Suit Wolverine, Dr. Doom, Scarlet Witch, Age of Apocalype Beast and Rogue, and the empowered-up Deadpool. Bottommost tier (heroes you almost never see used) is usually Spider-Woman, Mr. Fantastic, Thing and Luke Cage. The spaces in-between, though, are a bit more open to debate, especially since the metagame changes at different character levels and Playdom sometimes comes along and buffs weaker characters up to higher tiers.

* UnfortunateImplications: The [[TheSneakyGuy Infiltrator]] class is the only female-dominant one in-game, which is problematic because 1) [[FragileSpeedster they tend to focus on evasion and distraction rather than damage output, and cannot take a hit]], which 2) makes them unviable in [=PvP=] due to a focus on quick and heavy unavoidable damage as well as stealthy attacks (which Infiltrators cannot counter, thus making their class advantage significantly less useful), hence 3) making them unpopular amongst the FanDumb, especially of the sexist variety. This is in contrast with the [[TheSmartGuy Tactician]] class, which is generally seen as the best class. However, it only has 3 females compared to 10 males, many who are also limited edition and hence not readily purchasable for new players. This possibly reinforces stereotypes of TheChick relying on 'sneakiness' and unable to endure much damage, while men are more suited to be TheLeader.

* AuthorsSavingThrow: PvP had become a source of much complaining, especially with regards to the ranking system, which was changed in Season 9 to be much harder to get into the Adamantium League (not that it mattered, see GoodBadBugs below). What did Playdom do? Combine both ranking systems into one, so now, even if you don't have the ranking level, you may still have a chance if you're in the top percentage!

** Woe betide players when facing Grey Gargoyle (particularly since he's a MiniBoss in one of the best CP-farming missions), and his Creeping Petrification debuff. TryEverything (Neutralyzed[[note]]which removes secondary effects on Gargoyle's attacks[[/note]], high evasion to make him miss, etc.), and he will still inflict that debuff on a poor target.

** Also with the playable Loki, even though the game came out after ''Film/{{Thor}}'' and shortly before ''Film/TheAvengers'' the design for the boss Loki is that of the comics while the recruitable version is that of ''Film/ThorTheDarkWorld''.

** Nightcrawler, who like all other mutants, have been discriminated and hated by non-mutants his entire life. It's been especially hard for him due to his appearance. Despite this, he chooses to side with the X-men and then S.H.I.E.L.D. and fight for the humans who feared and hated him. Because of this he has had to fight his own mother Mystique a few times. Not that she cares.
** Karima Shapandar AKA Omega Sentinel who was brainwashed and program into a mutant-killing cyborg. In her Comic-book Collection story, she goes into a detail on how her insides were replaced with weaponry and sensors. After being deprogrammed does she realize who she was and that she can never be the same again.
** Thane whose life and death powers manifested as soon as Thanos came to Earth, accidentally causing the death of his people that helped healed. Then is pursued by the Death-obsessed titan for his power, [[spoiler: who is ''actually'' his father.]]
