What more does sakura have to do?

[Thane]

She could travel back in time, be of some use, act like a decent human being, as well as have some kind of intriguing personality and some interesting motives.

That would be a start.

None of that is training. He didn't do any of that in order to get BM, he never even tried to get BM, it was just a random perk of being friends with karuma. Sure he talked to Karuma, but is that really training? None of it has any correlation with that powerup.

let me start from the beginning :-

• Naruto always trained for controlling the power and the chakra from the beginning with his master ero senin check it out here its from the flash back

• Naruto then tried to tame Kuruma by fighting it and he did separate his chakra and it was like a tug of war. It was a part which helped Naruto gain control over Kuruma.

Gaining BM never happened in one day and was never meant to be that way either Naruto worked hard for and its not like any shinobi can appear out of nowhere and control Kuruma at will. Even Hashirama had hard time dealing with Kuruma.

In between the time naruto got KCM he all he did was TNJ to convince karuma to help him. I'm not saying he didnt earn it, but it was handed to him by karuma, just like sasuke was handed Itachi's eyes. He earned it, but he didn't train for it.

Sakura just got on par with Tsunade, not bad but not Sasukes or Naruto's level...
