Yes I was grouped with a monk, paladin, rogue, shaman and druid and the monk tried pulling one of these to the group and got nuked for over 2800 points. Later in the session when one practically blundered into the party the damn thing just stood there and repeatedly nuked the paladin down a couple of bubbles of health at a time. The shaman and druid were hard pressed to keep the paladin alive. These guys can be nasty until you get in their face and interrupt their spells. Fortunately they have few HPs and go down fairly fast once you start casting on them.
