while I agree the headbutting, fishhooking, and head stomping should be illegal in fighting, (although completely legal in a REAL fight) simply to keep the fans from watching people get MAIMED for life. But the rounds thing does take the sport from hard core to semi-sissy - also the whole idea of the REF stading up a stalemate on the ground. (neither would happen in a real fight, no ones gonna let you have 2 minutes to rest every 5 you fight, and no ones going to pick the guy off the fop of you so you can have a chance to punch him again. So keep the anti-brutality rules, but get rid of the rounds and fixed positions.
