I was trying to do Gossamer Crypt today, with 1 tank, and 2 DPS. We were trying to create a group finder for a healer, but we couldn't.
We chose "Event" and "4 people."
If we selected "enforce roles," the listing would ask for a tank, even though I was marked as a tank. Or a DPS, even though we had two.
And the bit where you're supposed to be able to select the number of players for each role, it wasn't editable. We couldn't change it off of 1 Tank, 3 DPS.
All three of us tried it, multiple times. And we never did get a healer (or clear it).
We didn't want to list it as a dungeon, because, well, it isn't, and people need the relic to enter.
We did learn that in order to change the dungeons from Vet to Normal, you have to leave the Night Market entirely.
