Like Gai said, it's pretty weird seeing a ninja only capable of using taijutsu. I mean, cmon, Lee has the chakra and such, but it sucks so much how he can't use that to a degree.
Regardless, his taijutsu more than makes up for it with his techniques, speed, and the ability to unlock 5 of the 8 chakra gates. Heh, imagine what he can do if he is at a jounin level. But then again, that level may be the same as Gai.
