said by Carpie:If doing random Q's, I wonder why not tank/healer combo. Duo-dps is going to create some wait time in there. Granted they'll probably quest in between but tank/heals is a good combo for that too. Pull as many as you can, Mind Sear tank for AOE dmg. Heal (if needed), repeat.
You only need to do the dungeons once so you get the quests done since they give a lot of XP the rest you can just keep questing with full heirlooms you should outlevel each zone in no time.
