Kishi handles Sakura badly
I just reread most of the war, and have to say something. Really, I'm no Sakura fan, but it's really bad writing how he puts her in and out of the plot randomly.
So, he didn't show her for 99% of the war. Then, as Naruto and Sasuke reunite, he goes all out, introducing her as the third main character, in one team and on par with the other two. She is with them kicking ass on the frontline.
And then, suddenly, when Obito returns from Kamui and becomes the Jin, Kishi completely forgets about her until a brief scene this chapter.
Either have her be a secondary supporting character from the start, OR make her a main character, but sitching her on and off like that is just stupid.
He does that with other characters too, but with Sakura it's the most obvious.
