It is is impossible to "make up for with heals" mitigation. Healing damage and preventing damage is apples and oranges. Now if you want to argue heals/ taps should be scaled down because we got mitigation that's logical I suppose. But simply crying it's not fair isn't going to make warriors more desireable in a more even tanking climate. And further more why the hell should knights be lesser tanks just to satisfy warrior egos? Can you explain why we should be worse at our primary objective without resorting to strawman 1999 class description arguments?
