before v2.1 HR used life tap before playing any card in hand, now he does the opposite. Also HR never uses life tap if "Doomguard" and couple cards are in the hand. It is very annoying! For exaple I had "doomguard", "Void walker" and "hellfire" and 5 crystals, in this sutuation HR played "Voidwalker" and ended turn with 4 mana!
