Re: You know, if Naruto had ended at the Pein Arc or five kage summit arc
Actually I think it's because she have full control over her chakra, she never shown a punch where she wasn't muti chakra controling (creating her seal), so I think it because she has full control over her chakra, her yinseal is nothing but more chakra.

And I think that if Sakura developed around the Pein Arc, Naru-Hina moments would be cut, so no Hinata development, and they both would have stomped pain, and less Naruto Development, So Sakura lack of "development was actually to develop other characters.
