I think it would be a good idea if we had a menu that would function like an Duty Finder except it would show all the groups that needed a healer/DPS/tank from the entire Data Center. You could find who needed a party, switch to that job, and join them! This will help out DPS queues a lot because there will always be a party for everyone.

This feature could also extend to those in queue for a dungeon. Imagine the help story missions will get...

New player on DPS: Wow! I always wanted to be a Dragoon! I can't wait until i get to Heavensward and slay dragons! *queues for Toto-Rak*

High-level player with tank/healer job: Gee, i can't wait for Alexander HM, lets do some roulettes for tomes so I can gear up for it. I wonder who needs a dungeon, *check DC party finder and sees Lancer*.
