The only major gripe I have of Naruto are the megazords, Susanoo, Kurama avatar, wood buddha ect. those coming into play really watered eveything down to a miniscule level in terms of character and power relevancy. It really leaves no imagination nor implications that other clans can compete or be on the same level without a giant avatar. I feel if the avatars had to be introduced, they should have been kept at a humanoid armor level, example Naruto's KCM cloak. Same for Susanoo, If you ask me, Madara and Sasuke would look much more badass in susanoo body armor (similar to Kurama in Boruto) than standing in a 6 story crystal nodule. Same for ribcage, it could have just fit around them measuring to the proportions of their body like a more condensed exoskeleton, but no, its one giant hub. If you ask me, fights would have been alot more interesting kept at that level, and alot of battles wouldn't have lost that ninja appeal. Example Taijutsu in susanoo humanoid body armor would have been nice to see.
