How powerful would nagato have been if he'd been taken to myobokuzan to learn sage mode? I think he could of done it his body was strong enough to handle two rinnegan when obito could only handle one even tho he had hashi cells and he had enormous chakra, plus it would of helped him immensely it seems like something jiraiya should of done, especially since he learned about the prophecy from the frogs you would think he'd take the boy to meet the people who prophesied about him.
