Looking for a way to kill time before MoP? Get out there and get some guild achievements. There are 26 Dungeon Guild Achievements just sitting there, waiting to be scooped up.
If you need incentive, I'm paying 500 gold for each Achievement. Any group that knocks out a dungeon, pick a spokesperson to PM me. I'll confirm the team and date of completion in-game, then send that person 500 gold, per achievement, to be shared among you.
It sounds like the DG2 beta doesn't start until late april or early may [link]
