1. You had to see this coming. At least I did at even the thought of Sasuke joining the war.
2. Naruto and Sasuke are the only ones that want to be Hokage. Kiba just has his panties in a bunch because of Sasuke. Naruto's and Sasuke's reasons for being Hokage are still valid and do not de-rail the plot.
3. Sasuke may be back to the good side, but he didn't say he forgave the elders for what they did. While it was a little cheap that he went from one extreme to the other I still find it acceptable.
4. I'm with you on this one. While I'm happy Sakura got development and became stronger, there is other ways than just giving her powers. Now out of all powers to give her this one is the best considering they didn't show her training. Because how can you show someone storing chakra. I would've like to see a little bit more on her training.
5. To be fair Madara can't even complete his plan unless he is completely brought back to life. To do that someone needs to use Samsara of Heavenly Life. Obito is the only person alive able to do so. As such he has to listen to him so he can be brought back and become a Jinchuriki to complete his plans. Plus Hashirama is his closest friend and greatest rival.
6. Kushina was trapped in the Reaper Death Seal so she couldn't get brought back. Mito wouldn't be able to emotionally destabilize anyone on the battlefield because everyone that was close to her is dead.
7. Ramen Guy showing up would be cheap. Ramen Guy solos Sot6P.
