@X29, your point with the Rasenshuriken is illustrating my point. Sasuke was able to copy part of Lee's technique because he was actually physically able to, but not the rest of it.

The Sharingan isn't a copier, it just shows the user exactly what's going on in whatever technique is being used. The Sharingan user can then use the jutsu themselves if they're actually skilled and fit enough, because they've seen exactly how to do it.
