Now that all of the MSQ dungeons have been fixed to have duty support and be able to run with trusts, I'm hoping that the dev team might go back and consider adding additional NPCs to run as trusts? If only because some of my most favorite dungeons are simply lacking in important characters that are actually there at the place and time, but aren't included in favor of random faceless NPCs or just doesn't make sense.

A couple of examples:
The Ghimlyt Dark (just added in 6.5) has only these choices. Hien as samurai (fills as tank slot and dps), Yugiri (dps), Alisaie (dps), and... random "Doman Shaman" for healer. Whereas this is the final big dungeon before Shadowbringers and there's plenty of good choices that are actually present! Like Kan-E-Senna for healer. Aymeric and Pipin for tank. Or maybe even the star of the expansion, Lyse? Why were only the above shown?

Baelsar's Wall: Most of HW duty support has your staple favorites (Haurchefant, Ysayle, Estinien) except, again, for the expansion ending dungeon. The one that should absolutely be including Papalymo, Yda, all the other scions that were present and infiltrating...

Ala Mhigo: Does well in letting Arenvald, Lyse, and Raubahn be there, but again there were other NPCs actually there and present! In the very opening cutscene you see Raubahn and Pipin rush in. Aymeric and Lucia later on, so on so forth.

SHB and beyond is all good because they were made with the content in mind and multiple choices, but please consider adding just a few more options to older dungeons as well.
