Personally, and its just my honest opinion, its not worth much, but if its not my honest opinion its worth nothing at all, i dont equate practice, dedication, and discipline with creativity.
To me practice=repitition, dedication=repitition, and discipline=repitition.
Indeed most martial arts follow this mantra , watch a karate class, and its the same move done over and over in sets of ten, then the next kata is repeated 10 times, then the next and so on.
Repeating the same kata over and over ,class after class is not creativity in my book, and indeed the response to a street fight scenario is to use those kata's, even the choice of which kata to apply is based on a set formula.
For me our "primal instincts" serves us well in the infancy of our species, but today one is usually required to curb them in favour of the law, and civilised covenants we all live under.
My "primal instinct" when someone blocks the supermarket isle with their trolley, is to give them an ear full and shove them out of the way, but this is unacceptable behavior.
Outside the ring, the behavior we see is assault pure and simple, thus imo what happens in the ring is a throwback to less civilised behaviour. The very fact that you can only legally do this inside the ring demonstrates that as a whole we as a society are moving beyond this behaviour.
Thats not to say that if i ruled the world i would ban this sort of thing, its something humanity has to grow out of in its own time on an individual by individual basis.
But imo part of becomeing a civilised technological society is to outgrow the primative behaviours.
