I think you're describing something that is inherent in TCMA and that creates a flaw in perception.

It's a dilemma. In order to perform TCMA correctly in application, you have to be willing to perform in correctly in application. Problem arises in a "moral" society. Throat chopping, eye jabs, joint breaking, face ripping etc - how do you apply those techniques? There's no suitable environment for them unless you're some type of commando, and in that case - a commando's MA all revolve around weapon retention and accurate shooting under pressure. Not fisticuffs - so it's a dilemma. If you had no inhibition and there were no chance for repercussion - what would be the best MA, what would be the best way to train?

One thing's probably for certain, you wouldn't have people like me saying we should do basic San Da training to develop a student's base because they wouldn't need to. The game changes when you have to worry about having your groin or throat ripped out.
