I 2-boxed this event last night. I was trying to get the earring for my monk, but it didn't drop. In fact, it never dropped in the years ago when I actually raided the event.
I parsed out 1,150,779 damage done to T`shara, but that may include a bit of regen as I forgot how to keep the T`shara from going DA.
I tanked this with a 2050 AA berserker that was buffed to about 4400AC and 32k HP. The shaman is just under 1000 AAs, epic 1.5, and ~24k HP with 26k Mana. The shaman's AA focus is on HoTs, Abundant Healing, Direct Healing, cures, buffs, and attributable DPS. It has almost no personal DPS AAs, if that give any reference.
