Rasenshuriken DID effect 3rd Raikage, his body just regenerated REALLY quickly. the sealing wraps were actually most of the way around his body but he recovered quickly enough to get out of them--it's clear to me he was out for a second but regenerated quickly, i mean you can see the cracks all over his body and it shows that he was out long enough to get some wraps around him and if he wasn't a zombie he wouldn't have regenerated at all. But Naruto HAS gotten Fkd up in Sage Mode, the dude has a point on that one but that doesn't mean sht about Sage Mode being bad or dull or overrated. Sage Mode is badass and Naruto genuinely defeated 3rd Raikage so you shouldn't try to take that away from him. but sage mode isn't infallable by any means.
Someone here mentioned Naruto could close his eyes and fight Itachi--i fully agree with that and have thought about that as well. he could do it in Sage Mode, or at the very very least his heightened senses would allow him to look at Itachi's feet for movement while also being aware of his upper body through the nature energy around him+his chakra sensory abilities. Add naruto's power and he has a real chance. The biggest thing in his way is SUSANOO. So Sage Mode Naruto vs Susanoo. I have NO idea what would happen. If he could hit with Rasenshuriken from behind and open the vulnerable spot like Danzou did, he would be quick enough to get through or get another rasenshuriken through. I don't know, I'm giving naruto the edge on this one. Just my thoughts, feel free to tear me a new one if you disagree. (although i'd prefer gentlemanly discussion)
