agree never felt this unfair, this is what will push people away from the game, more than lack of development..
Then you haven’t been playing long enough or paying attention. AoO launch DH was way worse. Ungoro launch quest rogue was worse. Galakrond shaman at launch was worse. KnC launch even Paladin with call to arms was way worse. Hell, recruit warlock from KnC was worse. Jade Druid, sticky fingers evolve shaman, Dr. Boom warrior, grand tournament secret Paladin, GvG mech mage… Hearthstone has always had imbalanced decks and the meta right now is far from the most unfair. OP is just salty though, complaining about curse warlock is ridiculous.
