Just tossin this out there, but with how the game is made, doing something like that would be pretty hard to implement code wise, not to mention cause more server stress than is already there. It would be cool to have, I just dont see something like this being able to be done specifically with this game. Duty Finder is a different story, since it searches the data center for people, party finder, you would literally have to make a different instance for people to actually join to make this able to work, like maybe a "Data Center Tavern" or something along those lines.
If it is considered to be made, it wouldnt be anytime soon, since it would take ALOT of work for the dev team to accomplish.
