No groin strikes, biting, scratching, poking with fingers, headbutting and grabbing fence/shorts.
That should be all.
These changes don't mean a lot due to the incompetence of many judges, only bad part of this article for me is the part that says 10-10 rounds should rarely be scored.
10-10 rounds should be encouraged, I guarantee that all the rubbish judges who can't be assed just pick a name out of a hat when they need to score a close round, that is why we see such strange scoring at the end of close fights. If you find it hard to score and you found no dominant periods in the round, score it 10-10 and forget it.
Then of course you'll have title fights scored 50-50, that's where the sudden death round comes in, another necessary addition IMO.
