When an art becomes a Just do it fighting, there is no longer an art.
Why? an art has to address how it's methodology in every different zones and components. an art has to address it's method.
there is lots and lots of people advocate. Just Do it, figthing is the best for fighting.... there is no art left but who is stronger, faster will win. and hopefully you got a new technics which others never know before so you can cheat and set him up to beat him.
an advance art is an art which address major zone's and issues. Not those just do it or fighting is the reality...... etc.
There has to have methodology in mind/body/breathing/power generatioin/technics of applications / tactic/stratergy to be an art.
Just do it is great if you are well build. But then even that, if others just grap a knive that Just do it will not work. Back to squre one.
