When healing in dungeons its a guarantee that you will win those healing meters. You will blitz it in every time, mainly because you are the only healer. Raid healing is a very different ball game. In my limited experience as a druid healer in BC, there were a few things that were very different from dpsing my head off as a hunter in the raid team. The first thing that struck me which was way different was, that in the raid there was a separate chat channel for healers. That was because we needed to assign healing, talk to each other about rotating our aoe heals, like the fabulous tranquility. We would occasionally discuss important matters like who stands in stuff more and who is easier to heal. We had an intimate detailed understanding of the raid team as healers that no dps or tank could ever know. We knew who was going to stand in the fire and who was going to skip out of it in a millisecond. We knew who was going to be easy to heal and who was prepared for anything. People who had bandages for example.
Communication was "Key" to the BC healing raider. And I must admit that I did feel like a member of an "in" club when I was healing through "SSC, Black Temple and Sunwell". We were "Mission Crucial" secretly communicating in our own channel, how to heal the noobs who stood in stuff. It was like entering a secret level of raiding that I'd never seen before.
Healing has changed. As far as I know there is no more secret communication between the raid healers. That is all about to change well in Riftwarriors anyway. The primary reason for this is because the shamman have copped a bad deal on the meters. Sometimes smashing it up on the meters and other times so low I can hear the shammy hearts breaking. The Pallies and the Priest who are tearing it up consistently, whisper to me mid raid "We need to talk about the heals after this raid" in serious tones which I know are going to lead to a close examination of the shammy heals.
I asked myself what's going on? I then went to the guildies and said "What's with the Shammy heals and the meters boys?". The font of all things WoW, that's of course Potter aka Icgankedppl and Who (that's who the Tank). "It's the bubbles Krin..the Pally puts a bubble up the Priest puts a bubble up the damage is stopped and so to are the heals of the Shammy and Druids". That's the short interpretation of a two day long discussion. I confirmed this info by searching the web. (see the links below)
The answer to the question then is for the good ol' secret world of "Healing Communication" to commence so that the healing is more coordinated, so the poor old shammies aren't throwing around their heals onto bubbles and not making the meters. From all reports Shammies are in fact awesome raid healers. That awesome healing rain is only making the meters if the noobs are standing in it. The tanks and dps can help out by running into the circle not away from them. Assignments for the circles and where to put them can be discussed in the secret underworld of healers, in the soon to be set up healing channel. I want to hear the shammy hearts singing next raid not breaking.
