- Focus on the core story of Strawhats, Roger Void Century, WG, OP, Ancient Weapons, JoyBoy, Imu, and ties one of those core themes to each arc, island lore and core villains or core arc characters.
- I'm tired of Luffy being an underdog, he has the burden to face and beat the Yonkou and WG already. Make Luffy's worth as a PK contender obvious and definitive at least powerlevel-wise, get rid of the ambiguity between him and Zoro, Kidd, Law, Yonkou Commanders etc, give him defining power boost that clearly outshine all everyone for him to finally step definitively into the levels of Yonkou and Admirals, and make all of the characters admit it.
- Since i like fantasy, i would suggest for Oda to give more fantasy themes in a few arcs, not every arc is about politics. The protagonists can do a treasure-hunting in a labyrinth-themed island, end up with an Admiral-level monster / creature as a final arc boss (for example, to tie the themes), they beat the monster, and get a crystal from inside its lair. A crystal which can store memories as a prize. And apparently - to tie the arc into the bigger saga - the crystal held the memories of The Princess of Ancient Kingdom.
