Bad reffing, is what pisses me off not judging. If by 3 or 5 rounds, both fighters are standing it's the fighters fault if the judges make a bad call. Judging is a subjective thing, so if you don't win by knockout or submission I say it doesn't really matter who gets the win. Reffing on the otherhand is what I have issue with(cough Mazzagatti). Some of the calls I see are so bad it's pitiful, they get too excited sometimes and make irrational decisions. The refs should always be bigger guys that keep their cool and know the mma rules better than anyone else. The Anthony Johnson thumb in eye incident being the biggest load of crap I've ever seen, Mazzagatti should never ref again after that one.
