I am looking for information from those who are becoming experience in the new cataclysm raid content. I wish to know what role each of the healing classes/specs are 'best' at in terms of raiding with the new cataclysm content. From my experience, healers get categorized as being best at either 'tank healing' or 'raid healing'; where tank healers focus primarily on keeping the main tank alive, and raid healers focus on keeping everyone else alive. So, could you all please chime in with your experiences on what the following classes/specs are 'best' at within the new content:
Healing Classes/Specs:
Druid - Restoration
Priest - Holy
Priest - Discipline
Paladin - Holy
Shaman - Restoration
