"He copied it flawlessly." Again. No he didn't. Curse Mark ensured that.

"Guy even remarks how impressive it is that he was able to use it as well he did." Gai also stated "Even with the Sharingan, it's not something that can be perfected that quickly" which goes to show that not everyone with a Sharingan can do what Sasuke did. Sasuke wasn't even able to copy the entire move, he was only able to barely perform a piece of the technique Lee performed. "You were able to copy /part/ of my t-"

"Regardless of how OP Madara is he did it. He copied a technique perfectly without practice or without ever using wood release beforehand." yes he did. Your point? Just cause Madara can do it, anyone can? It doesn't work like that. Madara can also discern Shadow Clones, so that means all Uchiha can right? He can also summon Meteors from the sky, that means Uchihas can right?

The fact that you still haven't provided a reference to the Sharingan being able to copy and allow the user to perform anything they see, proves you wrong. Sharingan can copy and memorize. But it does not give the user the physical capability of performing the action. If it did, it would be able to use Kekkei Genkai.
