I'm a healer. Just a healer. My guildmates have two characters, three, four or more. I've got an addon that does nothing but tell me who someone is when they sign in so I don't have to tax myself connecting one druid to another paladin. Me, I've just got a priest with a full set of healing gear and a solid set of DPS gear, if the need arises. Like many other healers out there, I've gone through heroics and raids; even ICC doesn't pose all that much of a challenge anymore. When you know what's coming and when, it's just a matter of hitting your marks.
Now the whole world is changing for all of us. The banal, practiced and frankly monotonous task of keeping guildmates and PUGs alive is going to go the way of the dodo, for at least a good long while. Challenge will be in the air again, and maintaining resources will be an issue for the first time in memory since my guild first cleared Iron Council.
For some of us, and I imagine this includes myself, this is going to be quite a shock. Unless we're in heroic or hard mode raiding content, we've been able to put tape over our mana bars. Now the tape's coming off, and I'm about to be pressured into a triage mentality I don't remember ever having to maintain. Either someone was topped off or dead. Only two possibilities, only two states.
I'm very much looking forward to the pressure to maintain an even shade of gray, to keep everyone between those two absolutes. I'd love to know how the rest of the healers are feeling about the cataclysmic shift in technique that is about to be gifted to us.
