Do the developers at this damn mercenary company have something wrong with their brains? Most of the Hero Powers classes cost “2” mana to use. And this this piece of shit game have 2 classes (Demon Hunter & Death Knight) have a Hero Power cost just only “1” of mana to use. Which is a incredibly unbalanced. Who was the retarded developer responsible for deciding at this shitty company that the Hero Power for about this two hero classes would only cost 1 of mana instead of 2??? You are retard Blizzard?
