I feel that Duty Finder is killing the community. Since it is here to stay, I would be ecstatic if they implemented:

-Cross-server friend list
-"Guesting" on other servers. Can easily visit other friends that are on other servers temporarily
-Cross-server communication

Duty finder is where we spend most of our time while running content, and yet the majority of people treat you like an NPC. The social part of an MMO is HUGE for most people, and this game is lacking it sorely. Giving players the option to talk to and play with people they met through DF would help tremendously.
