The running away wasn't too bad, seems more like the crew's just trying to get out of there. Hopefully they end up fighting the Sun God next chapter and things progress from there. If they escape and get confronted later, that'll just dragging things along. Chopper's here so hopefully he gets something to do this arc. If anything, Luffy expecting more from Usopp was nice. I'm pretty confident Oda will have Usopp leave this arc in a much better place than going in, even if it won't amount to as much as many of us may have hoped pre-timeskip for Elbalf Usopp.
