@Nidhoeggr:
Another reason why I hope we actually get a Davy Back Fight against Shanks. I can see both Sanji and Zoro being out of commission after Wano so if next arc is indeed Elbaf a DBF would be the ideal vehicle to give the other party members something to do.
I can see Robin, Franky, and Jinbe gaining more popularity because of the Wano Arc in the long-term. Maybe Nami will get more popular depending on how her fight against Ulti is viewed. Luffy, Zoro, and Sanji have been consistently popular, but somehow, I'm not sure about Usopp, Chopper, and Brook though, even though they have also been helpful.
I'm willing to believe characters like Usopp and Chopper will get more shining time at places like Elbaf. Chopper has been helpful as a doctor at Wano of course, though even that doesn't make me dismiss his potential as a fighter. Sanji has been helpful both as a cook and as a fighter at Wano, so if it's possible for Sanji, then I'm sure it's possible for Chopper, even though Sanji and Chopper aren't the same.
