Sasuke could have done alot of things which plot nerfed him also, like not using kirin after vote 2 explosion which heated up the atmosphereSasuke himself said he needed the bijuu.
If Naruto was actually serious, he could've defeated sasuke long before he absorbed the bijuu chakras into his susanoo.![]()
- he can use izanagi (I'm pretty sure he won't go blind due to the rinnegan) when they last clashed then sasuke appears out of nowhere and kills an unconscious/or heavily injured naruto
- he could have casted genjutsu on naruto while kyuubi was out cold (due to giving naruto his last bit of chakra)
-he could have used ama on naruto instead of using it on his chidori (due naruto not having chakra to use clock nor having the speed to dodge nor even sense it coming)
- sasuke was nerfed the first time he used ameno on naruto, he did'nt teleport close enough (like how he teleported madara to him with no space to react) he actually gave naruto some distance to both realise he teleported and the chance to react
- sasuke could have shifted naruto inbetween his attack and narutos (indras arrow and TBBRS)
Sasuke did'nt do any of that due to plot nerf
