Even then oda needs to get new people to manage one piece manga - like having editors to draw panels rather than doing everything by himself
He has pride as mangaka and wont ever do it.
Same as Togashi doesn´t want someone else to draw his manga.
You can´t change people like that.
And yes Shueisha is the problem here...
They milk to much One Piece and Oda with to many sides projects and fuck up Oda health...
It so annoying and we can´t do anything.
