This is how the fight should have went down!
Have Kaguya go all out
-All of the power of the tailed beasts
-All chakra natures and elemental KKG
-Truth Seeking Ball
-Rabbit Juubi mode
USE THEM!
Have Naruto give Bijuu Mode Cloaks to Kakashi and Sakura
If Kishi wanted teamwork he could have done this. Sakura didn't get a BM like the other Konaha 11 against Obito. This seems like a perfect time and her harming Kaguya would have made sense. Kakashi getting this would have been better than that asspull power up he got.
Have Obito use Perfect Susanoo against Kaguya instead of Kakashi
Again, better than that asspull. Have him die in battle too.
Mecha Battle
Rabbit Juubi vs. Ashura Mode Naruto, Perfect Susanoo Sasuke and Obito would been cool. However, Kishi denied us this.
All fails but Sexy no Jutsu saves the day
Kaguya kicks their asses and proves that she is threat. Naruto pulls out Reverse Harem no Jutsu as a last resort and it works! Kaguya gets a nosebleed and is temporally defeated. It shows that even through she is a powerful goddess she still falls prey to desires. It would have been funny and made more sense than what we got.
