It would be cool if Neji's 64-strike will disable the enemy's chakra use for some time.
I'm interested in seeing Lee's opened gates. It's always been cool in the anime, but on games, the fact that he loses health from doing it often makes it an undesirable technique, and it's usually not much more powerful (if at all) than that of the others' special techniques.

If they raised the health threshold that he can activate, that would be a different matter.
