Warlock killed me in the first 4 turns even after getting through my 2 taunts I was able to get down.
Priest I played never took damage.
Warrior burned me down in first 7 turns.
Getting to the late game with a mage is pretty hard vs skilled players.
I understand why people say the mage nerf was stupid. Against skilled players, getting past the 8th turn is a damn hard task... If you last that long you deserve a PB for 7-8 crystal with cheap SP minions to go with it.
I was winning quite a bit the last few days (almost all my games) and as of today I one 2 out of my last 15 games. Skilled players will burn a novice mage in no time flat with the warlock being (so far) the fastest win I have seen (in the first 4 turns).
