We had a 59 Warrior as MA and a 60 Pally as SA, with a 58 Bard singing AOE resist song, took approximately 2 minutes to drop. We couldn't slow him, but most the raid was low-mid 50's, the 59 Warrior was the only one to drop, and it was at the very end.
There was a total of about 20 People there, and only had about 4 clerics and 1 druid and 1 shammy.
Its not as hard as it may sound (especially if you have excellent teamwork)....the wait is the worst =)
