Well that's an explanation he wants to be specialized on sharingan alone, but that only answers to why bother to train sasuke all other questions are still on air and this explanation doesnt help at all to them, is like a patch. He knows a body changing technique, he is an exception, even all blood could be tranfered to a new body (if he knows a technique to change bodys i assume that he nows how to transfer blood), 2 sharingan eyes and 6 liters of uchiha blood... tada!

Im quite positive that orochimaru only wants sasuke to get mature, not "only" because he needs a greater container but because he wants a young beautiful body. Its original form (he was able to handle all his chakra) wasnt a 500 feet tall guy, just a thin average guy, i would say that even small.

I can found explanation to all things in the world, the problem is that they wouldnt make sense and would be contradictory as we see on: kakashi only needs sharingan eyes to use all their abilities with a littel strain, he expents too much chakra. Imagine naruto with 2 brand new sharingan eyes! he hasnt that chakra problem at all, he would rock, maybe not a true genius but well, on his own way his a genius (learnt a jounin lvl jutsu even not being genin, learned rasengan in a month, just luck?).

It doenst matter how i look at it im a blind distrusting guy who cant get it. Dont lose your time trying to enlighting me, lost cause [img]i/expressions/face-icon-small-smile.gif[/img]
