In most RPG games, mages are weak early, and insanely powerful in end game. And warriors are very strong early, but later become weaker than mages. In D:OS this is the other way around, warrior sucks initially, but near the end of game they turn to gods of war, annihilating anything on their way without problems, and mages are very strong on the beggining, and still pretty decent later, but at some point become considerably weaker than warriors.
