IMO, multi-job dungeons need to stay dead and buried. Forcing people to play as Jobs they did not like to get a party was weak.

Back when I had a character on Sargatanas in 1.23 I was fortunate enough to get a group of people who were willing to let me do AV runs as a Monk without having to change classes. Got through with no issues, no deaths even during Coincounter (to their surprise).
