Saying she has the same strength and disregarding new abilities is not really fair. You're right that it hasn't been cleared up but then people cry they don't know what it does but then they ALSO cry whenever she gets an ounce of panel time.
It's just silly.
I think her having fisticuffs with Sasuke would do a lot to redeem her character and show off her new toys that everyone is confused about.
I'm not disregarding her new abilities. Until now, things that we know objectively are:
- Sakura is more intelligent than Naruto and Sasuke
- Sakura is better than Naruto and Sasuke in terms of Chakra Control
- Sakura is enduring pain, she already shown that to us when she used her Sai Style Fake smile (hard times smile).
- Sakura
seems to be determinated. In the bridge battle, this was the same... and she fell anyways
- Byakugou is a seal that hold extra chakra reserves
- Tsunade's Byakugou Seal jutsus let Tsunade be healed without the need of making seals
- Sakura and Tsunade's raw strength is based on how much chakra are they capable to free in a hit using chakra control at the moment of impact. This could only be affected by the Byakugou if they can free as much chakra as the byakugou can give them, in one hit... in the case of Sakura, it's almost impossible, she awakened it for the first time.
What we don't know about this special technique:
- Improves strength? No proof, Tsunade fought Madara using Byakugou's Jutsus to not die in battle, but Tsunade without Byakugou Seal is already a strength monster (as Sakura), so until contradicted, Byakugou doesn't enhace strength.
- If Byakugou Special Jutsu enhace strength, we don't know if Sakura know about this jutsu. Sakura only have shown the Seal that holds chakra reserves and used it to Summon Katsuyu, no more, no less.
I'm not a Sakura hater nor a fanboy. I want to make it clear, I'm a Proof Guy. You can tell me again if what I said was really silly, or if I'm just make statements based on what the manga had shown us... Peace, sis.
PS: Only to be fair, I'll bring the Third Principle of Newton: Action and Reaction. If Sakura were able to do a hit that is too strong for her own fist be able to absorb the impact (the opponent is not the only who absorbs the hit, Sakura's fist does too), this could break her bones... so Byakugou's regenerative features could make some sense.
