Imagine if Wano was off screened and was replaced with Sakazuki Vs Kuzan and how Aokiji joined the Blackbeards. And how the fight with Black Beards and Revolutionary army occurred. And give more focus to BB and show how he gained his territories and developed his fleet. All this could probably take less than 40 chapters which leaves another 110 chapters to explore other interesting events the readers most want to expand on.
