suggest to add gates to one piece and start a new era of hunters so there will be balance cuz as it said some chapters ago that pirates are going to extinct cuz of this new powerhouses and organisations . and add some elements of other worlds in it so the worlds could trade or compete with each other .... ohh , and why don't you create something like World Cup but instead of sports make it that every 2 years all powerful individuals could fight each other in some kind of magical Colosseum that even if they kill each other , they will not die outside the Colosseum , jut being eliminated from future fights and put some kind of rewards , be it something like devil fruits or zanpakuto .
