We realize that there isn't a ton of incentive right now (outside of Heroic dungeons and scheduled raid tests) to organically form groups, and there is only the handful of beta servers rather than an entire region to draw upon, but we'd like to get as much feedback and testing of the feature as possible as we polish it. We're leaving Heroic dungeons locked in LFG for the time being, to encourage use of the Group Finder to form your groups.
For those who have yet to check it out, it's the "Premade Groups" tab on left side of both the PvE and PvP activity/queue windows.
