Personally i dunno why people hate it.
I mean it adds more stratigy to the game. Now you can't completely destroy your opponent, so you have to work a way around it. Usually Im a dominating dude on the game, but since stamina came around I've turned more into a high flyer, as they can use more moves than people like Big Show.
But they should tweak it just a bit, so you don't get too tired to quickly, it should also be affected by weight. So if you powerbomb sombody like Rey it doesn't take up as much stamina as sombody like Kane... it would take more to lift Kane than Rey
