History YMMV / WarCraft

** When Tyrande is swept downriver late in Sentinel Campaign in ''The Frozen Throne'', she is supposedly left alone to be fending off the Scourge. However, when she's seen again she has Wisps, Moon Wells, a tower, and a Barracks and troops there in the river with her.

** Even the Dark Horde remnants are not spared as repayment [[YouHaveFailedMe for their failure]] to accomplish what the Scourge were assigned to do instead. Adding extra irony, the Dark Horde faces annihilation against [[DracoLich Frost Wyrms]], undead equivalents of the remaining Dragons they control.

*** Goblin Land Mines can be this if used correctly; especially when used against buildings. As seen in [[https://www.youtube.com/watch?v=s9opu7egcRQ this video]], the player successfully destroyed Archimonde's base in the final level of the game by using Goblin Land Mines combined with the Invulnerability Potion to destroy all of Archimonde's production buildings.

*** Consumable items are now stackable, which makes for better hero inventory management.

** As mentioned above in ThatOneLevel, the {{Sidequest}} for ''March of The Scourge'' on Hard mode is almost impossible to complete as you would need to take a small army out with your Paladin hero to take out a Meat Wagon escort, even though those units you sent out would be much more useful had they just stayed at the base for the primary HoldTheLine mission. The easiest work-around people will usually resort to using is sending Arthas out on his own to cheese the Meat Wagons while under the protection of his Divine Shield spell. Especially so if Divine Shield is leveled up more than once.

*** In the Human Campaign in ''Reign of Chaos'', The Culling'', despite being a WhamEpisode in story, has much more straightforward gameplay than the HoldTheLine mission before it, ''March of the Scourge'' (More information under [[ThatOneLevel/{{Warcraft}} That One Level]]). You are racing Mal'Ganis to kill 100 villagers before he can convert 100 of them to zombies, and he launches some attacks at your base as well, but only from one direction and without an enemy hero leading these attacks [[note]]In the previous mission, you had to deal with attacks from three directions and two factions with a Lich in each side, and a third faction if you failed the sidequest[[/note]]. You naturally kill zombies faster than Mal'Ganis converts them, and Arthas does not have to be there to increase his counter while Mal'Ganis does. Killing him also knocks him out of the map for 3 minutes (90 seconds on Hard). This is also the first mission you have the heavy infantry unit, Knights. A few squads of knights can take down zombies at several different parts of the map at once without any issues. Also unlike the previous mission, there is no sidequest to worry about, Mal'Ganis is weaker than a normal Dreadlord that inexplicably has the Siege damage type this mission, which makes him much worse in direct combat. ''Reforged'' adds in some mini-bosses that appeared in World of Warcraft in some of the houses and buffs up Mal'Ganis to the level of a normal Dreadlord, so the mission is no longer as easy as it was originally.

*** The "Undead nuke" and the Human Alliance "Banish nuke" counterpart is one of the most infamous in the game's history. You take two Undead heroes, usually a Death Knight and Lich, cast Death Coil and Frost Nova respectively on what you want to nuke. Add in a third hero like a Crypt Lord or Dread Lord for Impale or Carrion Swarm respectively and you have a triple nuke. Impale is notable as it'll stun your target, opening them up for the Death Coil and Frost Nova combo. As for the Human version, you take a Blood Mage and have him Banish a target to make them WeakToMagic, then throw a Storm Bolt at them with a Mountain King to deal crippling magic damage and a stun; this is even more devastating against Undead when you throw in the Paladin's Holy Light on top. This can result into the quick death of even heroes below Level 6, and this nuke combo is hated by many players as the main recourse is to be quicker on the draw with a health potion, Invulnerability Potion or Scroll or Town Portal. This is even worse in team games with a Human ally and an Undead ally unleashing nukes to boosted effect.

When a Human opponent alone is battling Undead, the Banish nuke becomes very dangerous due to Holy Light's offensive application against Undead units on top of Storm Bolt's wallop.

*** In the Single-player campaign, Gryphons or Dragons are amazing for surgical strikes to trigger an InstantWinCondition. They're restricted on many levels for this reason as ArtificialStupidity prevents the enemy from using everything at their disposal to counter your flyers, and in order to encourage creativity beyond "send flyers to key targets & win".\\
\\
For instance, on the final level of the Human campaign in ''Tides of Darkness'', it's very feasible to fortify your starting base and use the goldmines in this sector to amass a swarm of Gryphons and bum-rush the portal (your ''only'' objective). Amusingly, this contradicts the [[GameplayAndStorySegregation ending cut-scene]]. Meanwhile, the Orcs can buff their Dragons with Bloodlust and Haste and send a flock with triple damage & doubled attack rates to eliminate key targets.

* ItsEasySoItSucks: Veterans returning from playing ''VideoGame/StarCraftII'' and/or ''Warcraft III'' will likely find ''Orcs and Humans'', ''Tides of Darkness'' and ''Beyond the Dark Portal'' to be on the easy side. The main challenge is are lower unit selection limits and clunkier interfaces but the computer opponents don't attack in a way that will be too difficult for a player with some skill at macro managing multiple production structures and building up a large army that will steamroll most opposition. Some levels have an EasyLevelTrick that takes away much of the difficulty, while the lack of infinite money scripts in ''Warcraft II'' means you can run a team out of money by attacking their gold workers until bankruptcy.

** Harpy Storm-hags cast Sleep to put your heroes out of action and Curse to make them miss half their attacks. They're not dangerous by any stretch of the imagination, but fighting them gets tedious very quickly.

*** The AI tends to prioritize weaker units first before stronger ones, which can be particularly annoying for the factions that have weaker ranged units compared to the melee units on the front line (Horde and Night Elves). This is particularly noticeable with the Horde, which their ranged headhunters have less than double the health of the melee attacking orcs. The result is the player spending loads of time micro-ing to keep the headhunters alive while the fighting goes on.

*** Rain of Chaos is a spell used by a few demonic aligned campaign enemies (Archimonde and a few Dreadlords). The normal Inferno spell is the Dreadlord's ultimate and will damage and stun an area as it drops a powerful Infernal, but Rain of Chaos casts that spell 2-4 times (depending on its level) and creates a force the strength of a small army almost instantly. The spell does not cost any mana and has about half the cooldown of Inferno as well. The only saving grace is that you can interrupt it if you stun the caster before it drops too many Infernals.

*** In ''The Founding of Durotar'' Act II, the final encounter of the Theramore Island submap is a brutal WolfpackBoss against a Mountain King (level 14) and an Archmage and Paladin (both level 12), while Rexxar's party is around level 9-10 at this point. The encounter also includes elite knights and spellcasters that will dispel Rexxar's summons or Rokhan's Hex. It is a huge spike in difficulty compared to the rest of the map, and not properly micromanaging the encounter will get your party shredded to bits.

*** ''The Frozen Throne'''s Orc campaign gives you a new GameBreaker every time you kill a new monster. Here, have a shield that boosts stats while setting enemies on fire, or a diamond that shoots lightning, or a stick that summons reinforcements while making your allies go faster, or a free ChainLightning spell, or a healing item that amounts to a fountain of health following you around... The biggest one, however, comes in chapter 2, where the shop at your main base sells relatively cheap Necklaces of Spell Immunity. Slap these on your entire party, then laugh at enemy spellcasters as you slaughter them with total impunity for the rest of the campaign.

*** In the ''Dungeons of Dalaran'' level from ''Frozen Throne'', there is a small area where some Blood Elf troops are stuck in jail cells that once freed go to the nearest weapon rack and arm themselves. However, if the player frees the spiders in the cell right before them, the spiders will get caught up in the trigger that has the Blood Elf units turn into stronger units, and go to the same rack and arm themselves, turning into useable Spell Breaker units. Considering thats basically more free units, nobody really minded.

** The only time we get to play with an Archmage in campaign mode is in two missions of "The Scourge of Lordaeron" with Jaina Proudmore. You are never able to level her up to use Mass Teleport and her absense means that the very helpful Brilliance Aura is never available to help your heroes and casters recover mana. Archmage characters, even if they weren't Jaina, could have added variety to the Alliance campaigns.

** Another minor one is that while ''Reign of Chaos'' did a good job in making sure that you got to play with each of the four faction's Hero units at some point throughout the story, there was one exception; the normal incarnation of the Undead's Dreadlord. This is especially odd when you consider that the Undead campaign introduced up to 3 Dreadlords (Tichondrius, Anetheron, and Mephistroth) that could have been provided to the player, yet they all basically just sat in the background while their new Death Knight, Arthas, did all the work. And sure, the player does eventually get to mess around with Varimathras in ''Frozen Throne,'' but Varimathras' spells weren't that of a pure Dreadlord. He was basically a half Pit Lord due to Carrion Swarm and Inferno being replaced with Rain of Fire and Doom.

** The Night Elf campaign of ''Frozen Throne'' spends a great deal of time building up the Night Elf warden, Maiev Shadowsong, as a key character of the story. However, she's pretty much forgotten about in the following campaigns as she gets one mission in the Blood Elf campaign to show that she's still hunting Illidan in Outland only to then [[WhatHappenedToTheMouse never appear again]]. One would think that at the very least, she would have continued the hunt to Northrend once Illidan's army begins their march towards the Lich King, which could have added a Night Elf faction into the mix for the Undead campaign. Her vendetta against Tyrande is a major influence on the story and another interesting plot point that could have influenced Maiev's character arc if it had continued plus she has a major bone to pick with Illidan.
