You of all people should know better than to equate rank with mastery.
I didn't make the rules!
(Of course we all get annoyed when you meet someone with a "grey belt" who must have tied it to the back bumper of their car and drove to the seminars - because after working out with them it is clear that there is no way that belt got so grey from their hard work.)
Anyway, my evolution in martial arts has gone the direction of internal martial skills to better power aikido, MMA, and weapons work. I believe that you become the mind you train. So that's something to think about when considering your personal martial evolution.
