History YMMV / HearthstoneHeroesOfWarcraft

* GoddamnedBoss: The Steel Sentinel, the second boss of ''League of Explorers''' final wing, has a very frustrating passive hero power that causes it to [[DamageSpongeBoss reduce all damage it takes to 1]]. Pyroblast? 1 damage. Deathwing? 1 damage. Not even the infamous Divine Spirit+Inner Fire combo can be used to cheese it, meaning that players are stuck grinding it out. Adding to this, the Sentinel's deck contains tons of cards that either heal it or give it armor, making the fight take even longer, and the heroic version causes ''its minions'' to only take 1 damage too. The only saving grace is that it's more excruciatingly long than it is hard, plus a Mage deck featuring Flamewaker, Rhonin, and Malygos usually does the trick in a quick amount of time.

* EarWorm: Many of the trailers have very catchy songs that people will be singing, and humming them for weeks.

** Signature cards, when first introduced in ''March of the Lich King'', were almost universally panned for looking bland and uninteresting thanks to them being DeliberatelyMonochrome, and the text on the card making it so it's tough to see the full art on the card. Come ''Festival of Legends'' and especially ''TITANS'', the signature cards were praised for hosting SugarWiki/AwesomeArt.

*** "Handlock" for a Warlock deck that uses card draw in combination with card text to play extremely strong minions early.

*** "Ramp Druid" for a Druid deck that uses spells to increase its mana crystals and play powerful minions more quickly.

*** "Handlock" is a Warlock deck focused around drawing cards and getting a huge hand in order to use effects like The Dark Portal and Abyssal Summoner.

** Snowflipper Penguin is a vanilla 0 mana 1/1 minion from ''Knights of the Frozen Throne'' which stands out among other pack filler cards by being [[RidiculouslyCuteCritter so incredibly adorable]] that no one seems capable of outright disliking it. Also, [[RuleOfCool it's a snowboarding penguin]]. To give you an idea, on Hearthpwn (one of the biggest Hearthstone databases and forums out there), '''84%''' of people who voted on the card's viability deemed it "Meta-defining" despite the card itself being entirely unremarkable from a gameplay perspective.

** Due to a combination of how the voice acting was directed and whether or not you're losing, the general consensus is that the heroes are a bunch of sarcastic shits in their emotes. Note that this doesn't really apply to Gul'dan, [[SmugSnake who's a sarcastic shit canonically]], Magni, Uther and Anduin to a lesser extent, [[NiceGuy who are very much sincere]], and Ragnaros and Jaraxxus, [[NoIndoorVoice for reasons you already know.]]

** On a more casual level, [[MechaMooks Mech Decks]] have becomes quite commonplace. This is because the neutral Mech minions all synergize extremely well, so much in fact you can make a Mech Deck out of virtually any class with the bulk of minions staying the same. Mechs also happen to overlap with two common strategies: [[ZergRush sending a bunch of minions faster than your opponent can remove them]], buffing minion(s) so that your opponent will have a ''harder'' time dealing with them. Mechs can also [[OhCrap combine these mechanics]] as well.

* EvilIsSexy: Many players will admit that [[TheTriadsAndTheTongs Aya Blackpaw]] is quite attractive for a Pandaren. She also happens to be the first example of a straight-up evil Pandaren in any sort of ''Warcraft'' media.

* SeinfeldIsUnfunny:
** The voice acting and visuals were outright revolutionary. Each individual minion has some kind of personality to them because of their voice acting, and the detailed battlegrounds and artwork made the game feel very much alive. It was the first card game to be ''immersive'', which was quite the draw. Every CardBattleGame since then has included these in the hopes of taking ''Hearthstone's'' crown, and among the fanbase they're mostly taken for granted nowadays.
** The game's barrier of entry is pretty steep, especially compared to more generous alternatives, but at the time of its release ''Hearthstone'' was the cheapest card game on the market by a massive margin due to both the in-game dust economy and the lower amount of cards needed for decks, as well as the fact that simple grinding could get you far. Over time, people decided that while it was cheap for a ''card'' game, it was too expensive for a ''video'' game, and despite efforts to reduce the barrier of entry via more free stuff and higher paying quests, the game's cost is still too much for some people.
