I dislike the whole rolling thing, it always struck me as unrealistic in BF2, you' d stand there (or couch) and lace a guy lay on the ground with automatic fire, and he'd just role on the spot and shoot u with a head shot, whilst hardly getting hit. Not gonna happen, you ever tred rolling and getting a shot off like that with a rifle, especially with a hail of bullets comming at you?

Personaly I hope this is a feature that won't get included, or if it does, then your whole viewpoint should role as well as your character just like in real life, where it would then be used to nip back into cover, instead of just to avoid getting hit, whilst lining a shot up.
