Just tried this on Aradune. It's currently in DoDH era.
Trio was:
SK - Lv 70 - 21k hp 1420 ac 1010 AA
Zerker - Lv 70 - 13k Hp - Most DPS AA's
Sham - Lv 70 - 12k Hp / 11k Mp - All heal AA's, most utility AA's
Ran in and tanked all three with SK and tried to burn down Spiritcaller. Healing became too much for the lil shammy once SK epic click wore off. Got him down to about 40%. If I had a cleric it would have been easy.
Things to note:
He rampages, not sure if it's AE or sing target. The zerker was getting hit for up to 1400.
His mana drain AE can be ranged. I stood outside of his room on the shaman and was not getting hit, but still able to heal my SK.
He himself hits for 366-1743 /w max shielding. Definitely triples, possibly quads.
His adds hit for 243-941 /w max shielding. Double attacks.
