History YMMV / DragaliaLost

*** While many people have been hoping for Agito to become playable (with Volk's beast form getting that before the anniversary), with how much of an obstacle Harle had been, him being revealed as the welfare adventurer for the first part of Faith Forsaken is not something anybody expected.

* TheyWastedAPerfectlyGoodCharacter: The "Caged Desire" Event involves a {{Crossover}} with ''VideoGame/Persona5'' and it's not fitting in all the other Phantom Thieves like Ryuji/Skull, Yusuke/Fox, Makoto/Queen, Futaba/Oracle or Haru/Noir people are upset about. It's more people are upset that ''Dragalia'' has its own PhantomThief in Lapis... and there's not ONE interaction with them in either the event's story or their individual Adventurer Stories.

** Grimnir's Trial puts you up against the nerd again, but whereas his original challenge was a joke, here he lives up to the self-issued 'war god' title. Forget shapeshifting to evade Nihility; Voidlight Eraser will beat you to the punch every time. As if that sudden downer wasn't enough, on his first Overdrive he'll set up a barrier around himself and the cyclones he spawns, which themselves will spawn a number of cyclones that bombard the party with unavoidable damage should they reach the far wall, and once those run out, he'll start attacking you through his barrier while you try to bring down those cyclones. If you're not paying attention or you're underperforming, you run the very real risk of losing your party before you can finally attack him again. Attempt Master undertuned at the peril of your own sanity.

** The September 2021 repeat of "Divine Deception" ran into this when it was shown that instead of running for 14 days like they usually do, it would run for '''41''' days! Considering it was announced Cygames would be cutting back on original events, it's got players worried, especially on the cusp on the 3-year anniversary.

[[spoiler: It is eventually revealed that Nedrick, and by extension the Agito, do not exist in Zena or Audric's timelines.]]

*** Nidhogg is a pretty easy boss to take care on in Void Battles, provided you have Enervation Resistance unlocked. His Trials version? Hoo boy. He not only has all his old attacks, he can also make a moat around the edge of the arena, squeezing you in much tighter, and if you wander into it, you'll be inflicted with Poison. Then, Nidhogg shoots out a variety of blue flames that you can't destroy. They'll wander the arena before stopping and unleashing purple [=AoE=] attacks, and thanks to the moat you have very little safe space and very little time to find it. As if that wasn't bad enough, once Nidhogg's health drops far enough, he spawns Shadow versions of himself that has all the same attacks. And since this is Master, all of those attacks are purple. Did I mention that the blue flames are still going? It's almost impossible to find a safe space to attack from and you'll be constantly bombardded by purple attack after purple attack. Also, the shades can inflict Enervation, meaning those who skip over Void weaponry to go straight to Chimeratech risk killing the run for their entire party. To make matters worse, the attacking Weapon types allowed during its first run are Lances and Daggers, most of which (including popular picks like Halloween Elisanne, Mitsuhide, Ryszarda. Sha Wujing, and Curran) are Curse Resistant instead, meaning you'll either have to go with a Poison Resistant Adventurer you either aren't used to or have built up[[note: The eligible Poison Resistant Adventurers are Wu Kong, Fritz, Annelie, and Malka]] or waste two Wyrmprint slots on Poison Resistance. Don't think Healers get a break either. With all the super attacks going around, you're gonna wanna have Regen healing Skills, but Hildegarde is another Curse-only Resister. Gala Zena resists Poison, but her heal isn't regen and healing Shared Skills take a ''lot'' of time to charge up. The only Light Healer with Poison Resist ''and'' regen healing is Vixel. Hope you've got him powered up!

* CatharsisFactor: The "Dawn of Dragalia" Event gave players the chance to lay the beatdown on Elysium, after essentially causing the main problems of the game in the "Forgotten Truths" Event. While his Universal Creation move can be frustrating in the higher difficulties, it's barely an issue in the lower ranks, and several Adventurers can outright bypass it. In particular, both of Alberius' Skills can pierce through the barrier with ease, allowing the player to brutalize the Holy Greatwyrm.

** Going up against a Light-element Boss that has Curse of Nihilty? Expect Summer Verica to be the Healer of choice.

*** Thor. Not only does have his typical spammy lightning attacks, but he also gets the same Curse of Nihility that the Sinister Dominion bosses have. As if the restrictions on Weapon types wasn't bad enough, due to the way the boss is structured, it's very, very dangerous for Sword users (like Alberius and Gala Alex) to attack. Poseidon, while still very nasty on the higher difficulties, is much more manageable, even if his constant dashes push aside Dagger users like poor ol' Notte.

** Thor in the Trials of the Mighty, especially on Expert or Master. Not only does have his typical spammy lightning attacks, but he also gets the same Curse of Nihility that the Sinister Dominion bosses have. As if the restrictions on Weapon types wasn't bad enough, due to the way the boss is structured, it's very, very dangerous for Sword users (like Alberius and Gala Alex) to attack. Poseidon, while still very nasty on the higher difficulties, is much more manageable, even if his constant dashes push aside Dagger users like poor ol' Notte.

** When Lilith appeared in the Trials of the Mighty, she was made into a Raid Boss. Unfortunately, her HP got jacked up proportionally, and even when you have four teams over 45,000 Might, it's still extremely difficult to claim victory, despite the time limit being 8 minutes. Her various attacks aren't too difficult to tank, but because she throws out so many purple attacks, the various CPU players retreat to avoid the attack, wasting valuable seconds not attacking, which just adds to the frustration. To make matters worse, the Trial is for Gala Cleo's Mana Spiral, which mostly just adds the Amp mechanic to her moveset. Many people are so frustrated by this Trial, much moreso than even stuff like Mars or Thor, that they're throwing in the towel for Master and just completing Expert instead.

** 20-7. It's a BossRush against all five of the Agito's second forms. You have to fight all of them in a row, hope that you survive all of the area of effect attacks and other nonsense they throw at you, all with the same standard number of revives. Good luck. You'll need it.

** Emile, despite his listing below. Back when the game started, he was one of the most frequent antagonists, and players hated how big his ego was despite being weak and pathetic. However, as the game has expanded and the list of bad guys has grown to encompass very serious and dangerous individuals, Emile has been left behind. Him being the constant ButtMonkey, the HiddenDepths given in the "Caged Desire" Event and Gala Audric's Adventurer Story, and his overall non-importance in the main storyline has turned things around, and now Emile has a signficant fan following. They wish for something to go right for Emile, culminating in him being made playable. It's to the point that, when Leonidas, Chelle, and Euden all got Summer variants in the "Stranded Scions" Event but Emile didn't, a lot of people were disappointed, especially when a piece of promotional art DID show Emile in summer attire.

** Rise of the Sinister Dominion ups the ante in difficulty, and all of them are nasty for different reasons. Know that they will both shut down most of your buffs and deny their effects (Curse of Nihility) and inflict DOT that can kill you if untreated with potent healing (Creeping Corrosion). Bring your best healers and all the Punisher Wyrmprints you can spare if you want to win these battles, and don't forget your dispels if you know what's good for you. The July 2021 Time pits you against Expert Lilith as proof that you're in for hell in a handbasket. [[RageQuit So, let's try for a little more agony this time, 'kay?]]

*** Water has Leviathan, Vodyanoy, and Gaibhne & Creidhne.
*** Wind has Vayu, Freyja, AC-011 Garland, and Roc.

*** Shadow has Ramiel, Azazel, Shinobi, and Juggernaut.

** Audric's Adventure Story ended with him escaping from his world and returing to the player's universe. However, despite Audric [[spoiler: being the younger form of King Aurelius,]] he is not involved in the main story from Chapter 11 on, when the fights between Euden and his siblings reaches a crescendo, alongside the reveals of Beren and Nedrick. Shortly before the 2nd Anniversary, the Fractured Futures rerun gives a Castle Story explaining why Audric wasn't around to answer any questions about these events. [[spoiler: He was away liberating remote villages for months, and when he returns, he finds that due to time shenanigans, nobody will remember him if he doesn't keep in regular contact. Cassandra is the only one who remembers him, and is working on fixing this. Chapter 16 also didn't see him assist in calming the crowd at the Halidom, which he likely would have some knowledge about, and the discussion about Euden's parentage would have been the perfect time for him to enter the main story, but he's still MIA on that front.]] It seems Cygames has listened to these complaints, as they made "Fractured Futures" one of the first Raid Battle Events available in the Event Compendium, and made it extremely easy for even new players to recruit him, indicating that they do plan on using him in the main story at some point.

** Despite also being ThatOneBoss below, Grimnir in Trial of the Mighty is also this for many players. His attacks are pretty easy to dodge, he doesn't have many unblockable area-of-effect attacks, and after you break his barriers, he will stay still for several seconds, and most likely everyone there has enough to shapeshift right then and there. Considering many Trials can go down to the wire, it's not unheard of to slaughter Grimnir with just under three minutes left on the clock.
