Greg in his Twitts said that the Animators don't ask Oda about everything, they just wanna know where the story goes before it happens, other than that they don't ask Oda what to draw or what to highlight.
They ask him about some confusion they have.. and that’s enough for me to trust them…
In fact, there is an SBS where someone asked Oda about Impel down Logo/sign… and Oda explained that he received the same question from Toei and proceeded to explain the symbol…
And in many other occasions he says that he gets questioned by them on some stuff or panels… and on top of that, there are episodes where Oda supervises them
of course he will not be involved in every single episode, but that’s to me is Toei trying their best for the adaptation of manga
their flaw was their bad animation in previous arc is now fixed
and we cannot complain about slow pacing when manga itself is slow paced… otherwise anime will catch up to manga…
And we will have many filler episode while the arc is active like Naruto which was so bad..
In middle of war, you get filler on some different island lol
I think they are doing their best
Oda is not helping them out with his recent level of writing honestly
