We ran the instance last night with a really good healer, a lot of DPS, and very little CC. We Cleared the whole dungeon with not a lot of trouble. The third boss is usually the killer one and will decide if your group is just farming the first 2 bosses or if you will be clearing the whole dungeon.

We had a Cleric, Tank (sorry don't remember exact class), Stone Arrow, Trickster, and Outrider.

For the 3rd boss, I respec back to Auramancy (became a primeval) just for the protective wings ability, which blocked all magic damage from the boss for a few seconds. This was insurance in case our healer got silenced.
