Nami/Usopp fight has ended with big mom saving them, Sanji has no matchup and were 30+ chapters in the raid.
I think you are getting too negative about things we don't know yet truly.
Ulti and Jack were used in the same way to highlight fast recovery of Ancient Zoans (essentially taken out quickly only to come back) We have no idea if Oda intends to have Usopp and Nami fight Ulti together. We have no idea if he plans to set up Chopper and Page 1 to fight now.
We just have no idea. Lets relax before we act like the arc is screwing over characters. They clearly could not handle the duo before but could potentially handle Ulti together. Chopper SHOULD be able to fight Page 1 at least if he recovers. Better than nothing.
