Well, the problem I'm having is that I'm also trying to queue for Tier 1s and do those for upgrades too. Sitting in the DPS queue = I go a long time not being able to get into the public groups doing zone events.
Always the case in MMOs. For whatever reason, most people want to be DPS. As such, DPS get long Qs, even though you need more DPS than tanks or heals. Only thing I can recommend is get another spec. As a healbot, I don't spend much time in the Q. Tanks are basically insta-Q.
