your saying that none have feats yet kakashi wins how? And (until proven otherwise) there saying its a finger genjutsu and why would somebody as analytical as kakasi not look at his finger? In a fight with a dangerous opponent or any fight in general you want to watch your opponents movement to be able to counter it.Has it been stated he was 12 at that time? Kakashi became a jounin around 11 because Obito became a chunin at 11. Yeah Kakashi graduated from the academy at 6 while Itachi at 7.
I never said Kakashi has feats in taijustu without his sharingan aside from the fact that he became a joinin and didnt even have a sharingan. But still they both dont have any feats in taijustu but Itachi still wins, makes no sense. Naruto got caught in it because he was trying not to look into Itachi's eyes, and looked at his finger. No sharingans here, Kakahsi wont have that problems.
You giving the reason for why naruto looked does not justify why anybody else wouldnt look at his finger
