No one posted anything like that
The ash bone disintegrates things upon contact, if sasuke's susanoo gets hit by the bone, then it would get destroyed too
It would do no better than kakashi's
Its impressive because Kakashi can now warp targets far bigger than before, and he can warp multiple targets simultaneously as opposed to before where he could only do the target he was staring at
Its impressive because sasuke got wrecked by chakra arms while kakashi got rid of them without any difficulty
No he got rid of them before it could punch him, sasuke couldnt
Nothing but your assumption that it would affect Sasuke's Susano'o in a similar manner. If you have proof, bring it out. Otherwise, don't pass it off as a fact. Secondly, the Susano'o cracked. It didn't crumble as Naruto's clone and Obito did. Another wrong assumption.
Doesn't detract from the fact that his defensive capability is still horrendous and without Obito's chakra, he would never be able to do this. Kakashi? Why are you using Kakashi's Kamui? Given that he has admitted, what, twice already that this is not even his power but Obito's?
Those arms and these arms are the same, right? Had they hit Sasuke's Susano'o it would have crumbled, right? Can I get any scan to back up this far-fetched self-created logic? Trying hard to gloss over the fact that a single, tiny little spike broke open the entire jewel from where the entire Obito handed chakra is oozing from. Lol Boy oh boy.
