Uh the warlock quest is still fine. You do understand one of the best performing Warlock decks doesn’t even play the big minions in it? It’s still a super power housed deck that keeps control from ever being played and nothing changed about its game except doing 1 extra dmg to itself a turn, which is stupidly easy to do.
The only deck that got destroyed is Shadow Priest because it no longer has Time Walk to shut the opponent out of the game and auto win.
I will agree the shaman quest change is pointless. That doesn’t even really delay it but MAYBE 1 turn and that’s a big maybe. It’s still not enough to make shaman oppressive. That deck has many bad matchups.
Pirate warrior needs a finisher card more than anything else. All the good and playable quests have a specific card that synergizes with the quest. Pirate warrior is the one lone exception that is left floundering after quest completion. I like the health changes but it remains to be seen if that really helps against the few decks that care about the board.
Mage is still better played from quest. Turn 7/8 lethal is easily doable and more consistent. I like the changes they made but they are a set late on making that deck build viable.
