Okay I don't care. Thats not what this thread is about. Point me to a Sasuke vs Naruto thread but this isn't one. You're a troll it's to obvious.I admitted that susanoo blocking out the IT was a feat but other then that. That's it.
BZ could have also told her about Rasengans and other jutsus but that doesn't mean she can use them. She's not a fighter. the only techs she used was dimension shifting which was probably most used for traveling and her bone techs. She ruled over a world where there were no shinobi at the time. Using her as an example is pretty bland seeing as she hardly had combat experience in the 1st place it seems. Furthermore, Tomoe Rinnegan is the final stage of Rinnegan seeing as it's the final eye that reflected out of Madaras head.It's not that it's beyond sasuke's ability to learn them, it's that if the assumption i made is right, he doesn't have the correct Eye to learn them.
If the techniques were created for the normal Rinnegan it doesn't mean the Tomoed version gets them. Just like Jutsu's created for the sharingan don't automatically go to the rinnegan.
Kaguya might not of lean't any techniques in her days but she must of known of all the rinnegans power due to black zetsu. Yet still failed to do so.
I don't see why he couldn't learn the 6paths. Think of it this way Nagato wasn't taught to use the Rinnegan by anyone. Yet he still unlocked some of the abilities Madara had. It's not for certain but Rinnegan techs might not all unlock in the same order.
