Thanks for taking the time to write here people, Just to clarify.. I said AoE healing spells.. meaning circle of healing, prayer of healing and holy nova. At the moment I am finding it easier to just mitigate in Disc when I raid heal now.. and obviously stay disc for Tank healing. I just found there was no point in hitting CoH or PoH when they would only really heal a group of healers. I think from now on if I'm organizing 25 man raids I want to experiment with spreading the healers among dps and treating the raid as 5x5 man parties with the tank healers in the tank group. Having raided a little more as a healer I see all of your points though.
