How do YOU heal?

I have eleven keys dedicated to healing on my Paladin, Resto Shaman, 3x Elemental Shaman group.

The first five correspond to the five characters and make the Resto Shaman drop a heal on them, the second set are alongside and are the more urgent heals where everyone will heal apart from the Paladin who'll try and pull agg/protect them, finally there's a single button for the "Oh God" healing where the entire party's taking damage and everyone'll heal another character. I also use that to 'top up' the party between fights quite often.

In addition to this I also run Clique to let all of my characters do healing with mouse presses. This is often used outside of instances where I can afford to be lazy and so the Resto Shaman becomes another DPS and the Paladin takes over the healing role- just a quicker way to kill without needing to go through the entire totems/pull/aggro/kill cycle.

i just use healbot and a smart heal macro . I run 4 shammys i have healbot on all the screens then i can click who ever has mana, if main healers stuned or silenced

1 Prot Paladin + 2 Ele SHaman + 1 Resto Shaman

Keys used [, U, I, O, P, and ;

Prot Paladin (Party1 or Focus)
[ - Mana Tap
U - none
I - none
O - /cast Flash Heal
P - none
; - macro for daily quests

ELE Shaman 1& 2
[ - Healing Stream Totem
U - /cast [target=Party1] Healing Wave

I - /cast [target=Player] Healing Wave

O - /cast [target=Party1Target, help] Healing Wave; /cast [target=TargetTarget, help] Healing Wave; /cast [target=Target, help] Healing Wave

P - /cast [target=Party1Target, help] Chain Heal; /cast
[target=TargetTarget, help] Chain Heal; /cast Chain Heal

; - macro for daily quests

Resto Shaman set focus on tank
[ - Mana Spring Totem

U - /cast [target=Focus] Healing Wave


I - /cast [target=Player] Healing Wave

O - /cast [target=Party1Target, help] Healing Wave; /cast
[target=TargetTarget, help] Healing Wave; /cast [target=Target, help]
Healing Wave


P - /cast [target=Party1Target, help] Chain Heal; /cast
[target=TargetTarget, help] Chain Heal; /cast Chain Heal
; - /cast [target=Focus, exist, nodead, help] Earth Shield; /cast [target=Player] Earth Shield

So,
U = heal main tank
I = heal self
O = heal main tank's target or target's target, or target
P = chain heal
; = earth shield focus or self

Since I have a tank, all 4 shaman have a macro dedicated to healing the tank directly, and I have a chain heal macro that targets the one down the list from them without targeting the tank.
