I have a full geared priest (guess his name :P ) he owns stuff but...
spriest is the worst dps in terms of dps
disc is the worst healer in terms of heals
so why are priests good? Sadly just 1 move, dispel. Without dispel priests would be the worst class in any mmo its kinda sad how our class relies on 1 spell that is totally broken in terms of game mechanics (I am talking only pvp here)
roll a mage/lock for dps or a shaman/druid for heals
or roll a paly if you feel like being a lamo
