I did BRD @ 52 and got owned horribly, 57 and had no problems. Pally/Mage/Mage/Mage/Priest team. I was 4boxing team doublemint and a buddy along who had a 57 mage with us...

The fire elementals were a bitch, if we focus fired them we could down them easily enough, on the packs later with 2 fire elementals it was a bitch and we discovered that Arcane Explosion spam with prayer of healing spam and a well timed invuln from the pally would normally kill the packs without much trouble... I'd say at 58/59 that would have been a LOT easier.
