i say dont stop fighht on the account of blood, if they pass out due to blood loss they lose, the rush them to the er and get some blood in them, or they can quit when they want. what i think they should allow in is kness on the ground if you front head lock a guy and he goes to teh ground you shld be able to knee the shit out of his head. i say no bitting, eye poking, ball hitting, scratching, fence pulling, or holding on to shorts. besides that eveything else shld be legal, head buts, elbows, ect
