Yeah I made the same mistake against a priest who had one of those "damage equals health" buffs.. he added a bunch of health, doubled it up, and BAM, got hit for 26 damage in 1 hit
I bought 7 packs for $10 and didn't get jack shit. Well I think I got one purple for paladin but I am not interested in paladins.
I go back and forth between mage and warlock. It's weird, I seem to go through streaks where I win 3 then lose 3, I wonder how much of this game is determined by luck of the draw.
