When he is around I don't think that Sakura can see anything else though Lol, her obsession over him is well known. Naruto deserves something better at this point, but you know the pairing never prevail in Naruto Lol.
Tbh she can make better Hokage than Naruto, but she's helpless in the front line...
I think she feels happiness that she never gave up on him and he has finally come home. I think Naruto is happy too and be the two of them being rivals again, I bet Naruto is smiling inside. But saying she was unfair to Naruto it would only be fair to say Naruto is just as bad after tossing Hinata away like that.
We can't judge it fully yet, but right now is not the time for solo attacks.
Sakura as Hokage I could see for one reason, she could handle the paperwork. lol
No but the entire point of that chapter is that they're all supposedly equal now yet they're obviously not. Being able to punch harder is just like if Naruto only ever learnt to make more shadow clones and that's it.
It's not impressive or redeeming, and in a war? It kinda IS about who is strong, especially when Sakura made it her goal to not be so weak. 3 years prep time for that? Disappointing.
She herself knows she can't compete with an Uzumaki and Uchiha based on power. Her Yin Seal helps aid her though so she can keep up with them. All she wanted was to be with them, all 3 together fighting side-by-side and her seal grants that.
It may have taken 3 years, but she surpassed Shizune who could never do it, so that's a start for her. Also, 3 years ago she was 13. Not bad and amazing chakra control if she stored it for 3 years straight, including her battle with Sasori.
