If you're a warrior and not shouting while fighting you need to pick another class as far as I am concerned
I am perfectly happy with the current system, it gives us something to do, is not really burdensome, and forces you to pay attention. It really is not an inconvenience, like pressing heroic strike 17,000 times a night.
I also like that we have something completely unique in a world where all tank classes are blending into a fuzzy bear wielding a shield and farting holy dust. If I wanted to be a Paladin, I would have rolled one, and the same goes for a Druid or a Death Knight.
Loyalty above all, except Honor.
