I have some:
A) Yamato was not written to be a SH and will not join the crew.
B) Fujitora is a waste of space and not up to par with what admirals should be.
C) Kaido statement about Adv. CoC does not preclude top tiers without it or even people in lower tiers having this power and could be applied to future vision without issue and be even more truthful.
D) Zoro fights are boring, because the formula is almost always the same: he starts cocky, get his ass kicked and them teleports behind the enemy and wins with a single strike. The only thing that changes is the amount of damage he takes before the teleport.
E) For the most part, Oda is a good storyteller. But his issue is that he has too many ideas and need a good editor to hold his reins. Otherwise you get wano.
F) BM in wano was a mistake that didn't add anything to the story and only detracted from her earlier portrayal. Her fight with Law and Kid is one of the worst things that Oda ever wrote.
G) The SH don't need other fighters or crewmembers. Oda is barely capable of giving panel time to the East Blue crew as it is. People that think that the final fight against BB will be multiples 1x1 while ignoring the grand fleet and the huge amount of allies they acquired are crazy, in my opinion.
