So I was looking on the SB promotional site, and I saw something interesting:

Trust System

In Shadowbringers, players will have the opportunity to challenge dungeons with a party of trusted non-player characters, including various Scions of the Seventh Dawn—though the traditional party matching systems will of course remain intact.
From https://na.finalfantasyxiv.com/shadowbringers/system/

It looks like it will allow players to enter dungeons with all their teammates being bots. I wonder if this can be used in Castrum Meridianum and the Praetorium to resolve once and for all the conflict between new players wanting to experience it properly for the first time and experienced players wanting to blast through as quickly as possible.
