The biggest reason I am looking forward to more content being soloable is the lack of players doing certain side content when I am playing through the game again on NG+ for my small livestream. Getting into trials and some of the raids for Endwalker took up so much stream time, and they are still too high level to be unsynced by just a few players. I found myself wishing, despite enjoying doing content with other players, that I had the Duty Support system to fall back on when players just aren't available.
