Now that we are locked into a spec when we put our first point into it, I think the RDF needs to only allow you to queue as the role you have spec'd into, or both of them if you have dual spec.
I was kind of surprised when it gave me the option to queue as DPS on a Holy Paladin, and in a leveling dungeon it was really annoying to bump into a Disc priest queue'd as DPS telling me (s)he could DPS or heal.
Wasn't the point of locking you into a tree and giving you specific tools to make you play the role you spec'd for?
Summary: Players should only be allowed to queue as the role designated by their main talent tree choice. (Choices if Dual Spec)
Comments anyone?
