The latest alpha build added NPCs that allow you to queue for older content, such as Dragon Soul Raid Finder, Mists of Pandaria Raid Finder, and Mists of Pandaria Scenarios.

You can queue by yourself or with a group for all of this content, and whoever is in the group will be able to enter the instance. There is no automatic matchmaking.

This pleases me greatly, I got alts who are REAL sad to have missed out on some old LFR transmog gear!
