Yeah, and Zojin just explained pretty much everything >> owned.
Also, I feel the issue of speed should be solved by considering those with taijutsu resets to be "specialist" in the subject. I mean whats really the point of getting the gates or the bone pulse if someone can simply claim to be faster and/or more agile than you; especially true in terms of raw speed. I'm not saying there wouldn't be exceptions to the rule, only that the exception would be of the vast minority if any.
