You are overrating kakashi and he can pawn a lot of shinobis with kamui but if he can get caught them but kakashi does not stand a chance against Naruto.I'm saying Kakashi can pwn all shinobi ever(with the exception of Madara and the sage..maybe Nagato too) with his Kamui. The Sharingan itself is the ultimate telescope for not losing sight of the enemy and the Kamui sends the enemy to oblivion, like Deidaras arm, and that was while Kakashi was moving very fast.
