Well, I have put a hold to the Bright Wizard of the Empire (Ranged DPS) and picked up the Dark Elf Disciple of Khaine (Melee Heal).

I absolutely love it. I may not be as potent of a healer as the Goblin Shaman or Chaos Zealot, but I can do far more then I imagined.

As the BW i was unable to kill Champion monster that were 2-3 lvls junior, but as the DoK I am able to kill Champion monsters that are 2-3 lvls my senior. RvR has been far more fun as the DoK as i can choose to use my minor heals to aid the front lines, join the front line in a melee dps support, or I can do both, in moderation, but both none the less. As the BW I was limited to only ranged support, and being highly frustrated that my attacks were being negated by the opponents healers... But when the enemy is not protected my healers, I can get the surprise attack in that could prove to be a nice dose of power.

Now in my opinion, the DoK is very similar to the Empire Warrior Priest. Both are melee heals, but for some reason it did not take off for me, but the DoK did... so despite the constant crashing of the game, I am Loving It.
