There has to be a voice of normality, and stop any sensationalizm.
Rob has already said that this is just freeing up boring clinch-matches and disposing of pure-power moves.
This is a small piece of the pie, as far as the full extent of the rules goes.

As Tony has already said, this generally wont affect 99.9% of the bouts.

There wont be a "NEW" set of "Lumpinee Rules" that will be separate.
This will only affect the power-kneer's/power-clinchers....and TBH there are very few of them outside of Thailand.

As far as I understand, the basic criteria for judging/scoring fights still stands as detailed in this article:

There is just being less emphasis put on pushing/throwing someone over in the last round, to show a physical dominance and steal the fight.
This generally doesnt happen in the UK anyway.

I think it is to also start doing away with the "pecky" little knee's that fighters do, to the thigh.....it gives the impression they are working, but in reality they arent "effective" knee's, and so gives the referee scope to step in and open the action back up.
