He was right. Given how awful the game currently is, and the fact this is the second expansion where they completely shat the bad...this could have more lasting consequences than the Galakrond Shaman debacle.
I'm only playing wild. Even there Demon Hunter seems to be pretty strong. Can't imagine how oppressive he must be in Standard mode :D
And even in STD, it's better than Arena. Literally every non-DH class averages under 3-3 in Arena ATM, according to HSReplay. 3 runs, not even bothering with the third because no DH offered. In fact, no DH offered in any of them, so you can imagine how bad it is to face such ridiculous cards.
