Routine breaks from the Straw hats in the New World. Nothing major, but twice an arc have a 3/4 chapter diversion to other groups doing things.
Yeah that's probably my favorite thing about Post Wano
We get to see other things around the world instead of getting the Strawhats' POV 24/7
Anyway outside of that I would...
- Give Usopp development and make it permanent
- Give Chopper a larger role and change his design so he looks more like a teenager
- Give Zoro more comedic moments (I miss the Tarzan yell)
- Reduce the number of side characters in every arc
- Bring up the dream of each individual Strawhat (outside of Luffy and Zoro) a lot more. I know certain members have dreams that will be completed over the course of the journey (Robin, Franky, Brook, etc) but there's no reason we can't see Nami drawing her map or Sanji looking for clues that lead to the All Blue every now and then
- Less fakeouts. People don't believe it when characters actually die due to Oda's terrible streak of faking out character deaths
- This is a bit controversial but I think we need MORE "filler" not less. Have the Strawhats seek out the Emerald City and connect it to the One Piece or something later. This would give certain Strawhats that shine outside of combat a bit more spotlight PLUS bring back the feeling of wonder and exploration that people loved pre timeskip
- More exploration period. Ballon Terminal, Vira, Raijin Island, etc would be great locations for the Strawhats to visit. Most arcs have
Man vs Man conflict but I don't
think we've seen Oda do
Man vs Nature yet
