Was reading some of the game changes. Streamlining the stat lines and armor bonuses has potential. The bonuses to spirit and mana regeneration will be improved which will make it a viable spec. This seems interesting, if they do it right. I would make a healer with +spirit instead of +int, since you would last much longer healing over time.
by the way, healing is not an art. Healing is downloading the right healing mod.
I hope they fix the game difficulty a bit though. In the burning crusade they whored out the magic items and saturated the AH with goods. It made level advancement much quicker and better for the casual gamer, but took a lot of the difficulties and fun out of the game.
