Well to be fair i dont remember the last time i could play control Shaman nor good old control priest on Wild. Or tempo something any class. The problem with Wild is not the class diversity, almost any class has atleast one deck that is "wild" level. But the real problem is archtype diversity in those classes. Like Priest is very restricted to OTK combos for example or going hard into Neptulon. The way the game works in Wild is very different to what i want my game experience to be.
Wait, what? One of the recent solid Priest decks was the oddball Darkbishop Benedictus / Shadowreaper Anduin / Reno deck. Unless you, for some reason, don't consider that a Control Priest deck.
