I like the concept of the 1/2 point system, I just think it still leaves room for debate and controversy. As the sport continues to evolve and fighters are more well rounded, I think too the criteria for judging must change. Recently we have had many bouts that have put the judges under scrutiny, however IMO under the current system of judging all of the decisions have validity to them. I think Big John said it that part of the judging should be damage done, yet that too can have cause for controversy. For example, fighters that tend to cut easily would be seen as damage, however in many cases it really doesn't effect their fighting (Guida, Griffin, etc.) Another issue is that TD's and sub attempts are held with more regard than escapes. An example of this (although it had no bearing on the outcome)was Sam Stout was caught in a serious Kimora by Lauzon which he escaped from, I wonder if the escape had any role in the scoring decision for that fight.
I think its abundantly clear that something needs to be done, we can only hope it is done soon.
