No.
I think it's way before, during the Pain Arc. I least that's where I felt that Sakura was dropping. More specifically when Hinata decided to "commit suicide". I wasn't expecting Sakura to jump in, but at the same time that moment was enough to get all NH wankers to go crazy over. The NS hug right after was satisfying, even seeing what I believed was Hinata's face of approval, my inner self knew that Kishi was going to bring in NH again. Then we still had Sasuke, so I knew it wasn't over yet.
Imo, Sakura went downhill from Pain. Before Sakura use to share pain with Naruto/ and was more developed, like the chapter involving Naruto going four tails I believe. That was an amazing NS moment imo. Also with her growing relationship with Sai, and being less of her part 1 self. But suddenly during Pain, she unexpectedly took the back seat more than usual. And to be honest, I see ch. 436 deserving to be an NS moment rather than NH. Some shippers say that that moment was an NH closure, but that moment was too out of the left field. In part 2, up until ch.436, it has only been NS. Now all of a sudden Hinata confess her undying love for him?
That's where I felt that Kishi had second thoughts from his peers. It didn't bug me too much but it was annoying how Sakura took a unexpected back seat up until the last chapter of the Arc. I was cautious but okay after the Arc, but then it went downhill since than. I never seen any meaningful moment from Sakura since Pain, and any moment I seen was over shadowed by NH, SN, and even before than Shikamaru. I lover Shikamaru, but we never received an Arc or pivotal moment that solely focuses on Sakura's battles. Even Sasori's fight was cheap because he supposedly committed suicide, the only good point was seeing Sakura fight. I thought the Sasori battle was an intro into Sakura's future potential, rather than a battle I hope she'll win in the end. Kishi just drop Sakura's importance as one of the main characters/heroine after the Sasori fight, but her development was doomed since Pain.
