Which fights? Zoro and Sanji? It doesn't take two full chapters to set up a fight. Oda can progress their storyline in 2 pages of each chapter. Everyone else already has a fight. As for fodder and non-main characters, they aren't going to get full battles. This isn't bleach. You must be imagining we'll get a 5 chapter Hawkins vs Killer battle. Or I can imagine in thriller bark going "Oh but what about the General Zombies whos gonna fight them?"
I’m not expecting sanji to get his fight for at least 4 chapters, we are close to it but I’m not expecting it next chapter it doesn’t make sense especially when his named chapter is coming up and there’s other things to focus on since they need to actually go to the live floor.
Also the big mom pirates have matchups imo. I think killer is gonna fight smoothie so that will be set up soon.
Zoro getting healed and getting up probably won’t happen for around 10 chapters.
