That was also one of my biggest gripes about the UFC game, other then the shine and legs kicks don't matter. To me they completely neutered the BJJ and judo guys. No way should a black belt struggle to submitt a person with poor submission skills.
Their ratings really didn't matter at all. You could take somebody with 93 sub offense vs a guy with 33 sub defense and you still would struggle to make them submit. It made no sense at all.
But usually in business, companies tend to borrow their competitors ideas and make it their own. So I hope they play the hell out of EA MMA and borrow some ideas.
