I would like this very much.
Unfortunately it's too much to ask for to queue up on multiple jobs for multiple instances.

For some (dumb) reason we're not even allowed to queue for more than 5 at once. Yet there are times like the Zodiac quest that require more than 5 dungeons simultaneously.

The current queue system is pretty antiquated and could really use an overhaul. I feel like we haven't had much updates since 1.0. What got added since then besides new dungeons? PVP Matchmaking, and Roulettes, and Duty In Progress. I think that's about it.
