My argument wasn't torn apart though. If it was, then show me where as opposed to making claims that it was with no explanation.
It doesn't matter if he was going blind or not. Even if he wasn't going blind. he wouldn't have done any better against 5 Kage. That point Naruto said if they fought they would both die. That was also before he received his powerups of the Tailed Beasts and the Sage's senjutsu.
There's nothing "fanfic" about none of those abilities working on Naruto. It's the truth. Explain to me how genjutsu would affect Naruto when Killer Bee already said genjutsu doesn't work on Jinchuriki who control their Tailed Beast. How would any of those abilities cause Naruto a problem. If it's truly false then explain it. Your excuses of "you saved me the trouble of doing it" just shows you have no rebuttal to that point.
As far as Sasuke always beating Naruto, do tell when. If you mean the battle at the Final Valley, let me remind you Naruto LET Sasuke win that. Sasuke made a bet that Naruto wouldn't be able to scratch his headband. So in their final clash, Naruto pulled back his Rasengan so he could scratch Sasuke's headband and win the bet. It was already said and shown the Rasengan is far stronger than the Chidori.
You seem to be forgetting it's named "Naruto", not "Sasuke". Thus, in the end Naruto will win, and he isn't going to be killed. Not to mention he is confirmed alive considering he is in the Last movie, which is canon by the way before you try to claim it isn't.
