Was able to box this mob with my level 85 Tower-geared WAR (6900ac with self and clr buffs) + rouge merc and level 85 clr-bot (mostly group stuff from Brell's Rest) + clr merc. This event really is a test of endurance as it took me almost 30 minutes to complete (even after 15 levels).
Had the CLRs run a complete heal rotation and once the merc ran out of mana I placed her in passive mode so she can regenerate, then placed her back in action. Killed the adds as they spawned. CLR-bot just unloaded cans of undead-DOT whoop@$$ on Tan'lor when mana permitted. :)
Max hit on my WAR was around 3.4kish, averaging around 2k. Mob dropped Tan'Lor's Earring, which was spammed in General. No one took it though. =(
Guess everybody is just TOOOO good for level 70 loot now-adays, even for their alts/bots.
