I honestly think that the huge mess that was Wano battle is only a prologue to what kind of mess the final battle of the manga will be.
There is another bigger concern - wano, WCi and Egghead - all these arcs ended with no plot resolution for readers.
Oda keep on saying we are nearing end game yet we keep on getting unfinished business related to these arcs.
With all those buildup in the first halfeof the arc, and in the end we are still left with unsolved puzzles - readers are left with lack of contentment or fulfilment.
Which makes me believe, oda is so immersed in writing the story as he desires that he no longer keep readers perspective in mind - the audience.
It's like I am directing a movie but I don't care about the audience at all
