Skimming through the 633 discussion thread, I saw many of the same complaints from multiple members. The four most common I've seen were "it did not advance the plot", "everyone received powers too late in the battle", "Sakura went from Jonin to Sannin too quickly", and "everyone is turning this into a competition when in war."
++You HAVE to have bountiful action scenes in a shounin manga when it counts. You just have to. Naruto is not the type of manga where you breeze through the plot with sheer dialogue. The anime would be in worse shape than it is without action scenes. Without the manga outlining "who does what and how" for a few panels, the anime would take off too quickly, it would catch up to the manga faster, and there would be even MORE filler episodes (which, last I checked, popular opinion states members hate).
++Which shinobi received which powers, now? The closest shinobi I found in the latest chapter that "gained" a power was Shino. Except Shino had this bug the whole time. Recall his words:
He had these bugs "in his system" the whole time, but when he sends them out to attack his target, he feeds more chakra into them so they become chewing machines.
Hinata had a partial 64 palm attack. She maximized at 32, but was at her limit. Through another realization of her convictions, she pushed forward and finally hit 64. Now she is going to try 64 palms with her Twin Lion Fist technique(?). This is simply another development toward techniques she already had.
Ino-Shika-Chou just took techniques they already had and made a formation out of them, Shikamaru humorously fashioning Chouji into a ninja tool. These are the only guys who are using strategy, using techniques they already have, to perform them in different manners to have different effects.
Kiba simply grew another head out of a shadow clone and developed his technique one step further.
++Given the fact that Sakura finally formed her seal, would it not make sense that she would be more than qualified to summon a similar version of Katsuyu (since Katsuyu is by Tsunade)? So the manga didn't portray her as having this ability in the past. She was likely more than qualified to do so even before the Fourth Shinobi War started, given her superiority in chakra control, but the manga simply did not give her the panel time or plot to show it until now. She had the ability to summon Katsuyu (or her variants), but was not given the plot opportunity to use it.
++What drives hard work to make your peers to their absolute best and keep their minds off terror and fear of death? Friendly competition. You see this in so much media that it can be regarded as a trope, so it's not as if Naruto is the first to display such behavior in a life-or-death situation. I would rather the shinobi focus more on the fighting than on whether or not they will live to see their home again. You keep that on your mind, where are you now? In La-La land. You're distracted! You slip up and the Jubi will fill your body with spikes (I'm sorry, too soon). The point I'm getting at, there is a...well, point to it. Competition is what fuels the desire to do better, which puts the shinobi at their absolute best.
