I think the concept of octagon control via top position or keeping someone pinned against the cage is the main problem. Would it be so awful if we threw out octagon control and went entirely with effective striking, perceived damage, and attempted submissions?
As it is, it's far too easy (and increasingly more common) for a wrestler to win via "octagon control" while making the fight boring, inflicting virtually no damage, and running out the clock on fighters who are trying to engage.
I really dislike when people say this as the fact submission attempts are scored is just as faulty, we see people use submission attempts all the time as a distraction to gain an opening to either attack with another sub or improve position. Since they are not really intended to as a submission why should they be worth points? Then you have strikes that aren't meant to do damage but rather to set up a TD or a big shot, should they count since they don't do damage?
