Nah dudeHave you guys forgotten the Kakashi Chronicles? Without Sharingan his chances of hitting his target is slim. That is why Minato said that justu wasn't made for him.When he acquired Sharingan, it enabled him to keep up with his target while he was moving at the speed he was going.
With sharingan Kakashi. Without Zabuza almost embarrassingly Zabuza will rape him like he was in prison.
And I'm not sure don't you have to have sharingan active to use the other jutsus that you copied?
