Well since I have paladin: I avengers shield the furthest one back and run up the other and stun him. That one goes down fast, all the while I have to watch my shaman to see if that other bastard drops a void on them. Once the first one is down and if there is no void zone dropped yet I can usually kill the next with standard dps rotation. One time I wiped before even killing one as they instantly dropped a void on my shaman and while moving the shaman the other dropped one on my tank. I just stared at the screen for a second realizing that either: A. my dps is going to die or 2. my tank will. I was pissed that TRASH had wiped my party in about 6 secs =(
