Just as the title says, these 2 decks are ruining the standart gameplay.
Control decks are unplayable because of quest warlocks, nerfs dont make the cut because warlock have way too much heal to be dealt with, unless you are playing aggro with perfect hand this deck is unbeatable.
Quest warrior on the other hand was already strong deck and mini set buffed it to the extreme, it is way too oppressive way to easy to finish quest.
Here are my suggestion Warlock quest no longer includes fatigue damage so control decks have chance against it.
For quest warrior, second and perhaps third part of the quest should require 1 more pirate to finish.
Both quests are way too oppressive compared to other quests, they should be brought down to others level.
