Just thought I'd come back and give you guys an update. I ended up rolling 4x cleric, 1x mage. Just hit level 30 today, it was going really quick with the bonus XP this week.

1 - Justicar tank
2 - Chloro
3x - Inq/Just/Sent

I started out with one of the clerics as pure healer spec, but I found that as soon as I got reparation and the important talents on my chloro, my healer specced cleric was doing almost nothing, so I specced him back to Inq. I set up mapped keys for each ability and a hotkey with 4-5 steps with delays between each step. Sort of like a fake castsequence. Put Healing Breath on round-robin, so it pops a 450-500 point instant heal on the tank every 2-3 seconds, plus whatever the chloro is healing for. So far I've cleared Realm of the Fae, Iron Tomb, Darkening Deeps, Deepstrike Mines, Foul Cascade, all at equal or lower level (as soon as the random dungeon queue started putting me there, since that's all I've been doing to level :P)

Having fun so far!
