As you can see, Naruto will die if he uses Kage Bunshins. I now I said in my previous post, that it would be awesome for seeing Naruto using KB in his R- Mode with Rasengans.. though I forgot this crucial information.
- But then again; they also said that he can't expand his Sage Mode limitations and what did he do in the end? Yes.. he found away. That's always with Naruto: he WILL ALWAYS surpass the limitations of his jutsu's by pure confidence and his love in his heart for saving his friends.. gives him the necessary boost for achieving every exceptations.
