I did this solo with a druid at 60. Its true that the mobs in the room are no longer elite and thus is now solo-able but the priestess herself is the real problem so here's the tactic I found when fighting her off for druids:
Fight while in cat form, accumulate combo points, fight till her MANA is damn low (don't worry, she casts tons of spells in a short period of time), in fact, till you think she doesn't have any. When she starts to heal (and furor will greatly help with this next part) switch instantly to bear form and bash her to stun her, then switch back to cat form, wait for your energy bar to fill up as much as possible, or till stun ends, whichever comes first, and then hit her with a ferocious bite and hope her health was low enough for it to have killed her. The problem with the priestess right now that makes her DAMN tough is that when her mana is low, next to nothing, her regen rate gives her JUST about enough to cast a greater heal that fully heals her. Unless you've got DAMN good gear and dps (and a stun or silence), she'll manage to throw one off every time.
Plus, not sure if anyone's mentioned this, but I think the name of this quest is based on John Carpenters 'into the mouth of madness' where by the end of the movie the guy believes he has to do what he must and tries to kill someone.
