Priests are squishy as hell when Pain Suppression is down. PVE is a bit better but not much. I ran a team to 70 and retired them almost immediately as they had so many faults for the way I played 'em. That was when I switched to priest+4 locks, which was a much more capable and lethal group. 5x mind blast is lethal as hell but it gets much less so when people get resilience. Fear Ward on everyone plus WoTF plus trinket was godly but that's being nerfed apparently. And holy priests just plain suck on offense until you gear them out the wazoo.
