That sounds true enough, and developing more ways to help people stuck on such a threshold is one thing that I think would keep them from falling back on excuses.
Contrary to the spirit of Eyebeams' rant, perhaps sticking with less "hardcore" training if you're really interested in martial arts is a form of stagnation? Of not upping the level of your training even when you know you can. Just a thought for discussion.
One of White Wolf's VPs is a sanda guy, actually. He destroyed a counterpart from WotC in a charity boxing match three years ago. Then again, I think the WW guys took it more seriously than anybody else.
Lastly, Eyebeams: since you write RPGs, you really should become an ultra martial arts badass. That way, when people make disparaging RPG nerd remarks, you can savagely kick all their asses and totally upset their expectations. As they lie broken and bleeding on the ground, you can sneer, "I read Stephen Kenson's Shadowrun novels, I *liked* Talon, *AND* I ripped you all to shreds. What does that make you!?"
Doing something like that would be worth at least 5,000 EXP.
