In an effort to fix DPS queue times I think they should encourage more people to fake tank or heal.
For example give 3x the xp or the transmutes if you queue as tank without a taunt and in all light armor. Maybe 2x if you queue as a healer with no group heal. I dont fake role because I'm a man of my word (if I queue for DPS, i DPS), but something needs to be done about the queue times.
Another way would be to enforce a certain competency on the DPS. Too many times I heal or tank a dungeon and the DPS are doing a combined 15k, with my optimized buffs. There should be a minimum dummy requirement of something like 70k (you can do this on a level 10 in white crafted gear) to be able to queue as DPS
