Ok I agree with the first.. I'm not completely understanding what you're saying in the second part.
Why would a Ration jutsu overwhelm two futton jutsu when ration is weK agains Futton? Plus Naruto jutsu was Senjutsu enhanced as well.. if anything, it's a testament to how strong Indra's arrow really is that it was overwhelmed.
I thought one was wind style while the other is not? idk I could be wrong.
Yes, naruto's jutsu was senjutsu enhanced, but if Sasuke's Indra's arrow was enhanced with senjutsu like naruto then his jutsu would overwhelm naruto's jutsu in sheer power regardless of element advantage.
Sasuke has the rinnegan meaning he has six path chakra and naruto has Rsm meaning he has six path sage chakra. It's an automatic six path chakra vs six path senjutsu battle. When Sasuke enhanced his six path chakra with biju chakra, naruto responded by enhancing his Biju chakra attacks with all of Kurama's natural energy cancelling each other out.
It explains why Sasuke who was at an elemental disadvantage was able to deadlock in such a high jutsu that greatly exceeds all non rikudou level character.
