Well it's true it is about beeing strong nothing else..

But it is still unfair looking from Lee's perspective. But Sasuke is an Uchiha and a Genious so thats always unfair in the real world to.. you can sit in school with a math problem for hours and hours and in comes a bright kid or someone who fids math easy and solves it in 1 sec.

Sasuke isnt as fast or a good as Lee is yet.. They say that it will affect his body using it for a long time.. thats where the differerance is..

And I dont know about this but.. Kakashi used his Sharingan when Lee opened the gates.. he only used the Sharingan then was it?.. just to keep up. Or did he use the sharingan before too?.. Cause that could explain why Sasuke learned how to fight like Lee even after the first encounter.. Kakashi could have copied some moves and shown it to Sasuke and let him copy them?.

I try not to see the chars bloodline's and abilities as cheating or cheap.. I just argue about them when ppl are calling Gaara cheap If he is cheap then everyone else except Sakura and Lee are cheap.
