Mentioned this before but I think this is how the rest of these fights may go down:
- F6: ~low priority. Most of them were introduced in Act 3. Best to get them down first and give some Strawhats the fights they need.
- Orochi and Big Mom's "#2's": Fukurokuju and Perospero functionally have bigger roles to play as characters than the F6 did. So it's clear why they aren't down just yet comparatively.
- Supernova/Calamities: Not sure whos exactly more relevant yet but between Apoo/Drake/Hawkins/Killer, 4 supernova who've been in the story for 500 chapters, and Jack/Queen/King vs Inu/Sanji/Zoro, 3 opponents who are highly relevant to the arc and winning the battles, either will be addressed first.
- Orochi/Big Mom/Kaido: Primary arc antagonists, should be taken out last
Sprinkle the Numbers in at any point and maybe Big Mom's crew if Oda feels like it towards the end to give the crew more than just fodder fights directly/make things more desperate
