5 man macro need guidance

Ok ive been here awhile did it for like 8 months took a break and now back. My question is i need a cpl answers instead of just one its like buying a car look at more dont settle on first. My team is dk 3 ele shamans resto shaman or dk 2 ele shamans mage resto shaman. Is there a way to say bind healing wave to one button to heal my tank but on same button say one ele took damage to heal him. Same thing with the cleanse spell. You click it it removes from tank click again removes from another shaman and so on. I want to try and keep my 4 and 5 buttons on resto shammy to riptide and natures swiftness and 6 7 8 for lesser chain and healing wave. But each one has the ability to heal any member in group. Dont know if it is possible or if anyone has a good way to be able to heal a group in an instance. This is my first group that consists of having a healer dedicated.

Kind of.

A button will do what you define it to do.
It won't sometimes act one way, and sometimes another.

I've personally got a few buttons, which heal a specific toon.
The addon Jamba is very highly recommended.
One of the features is that a toon can announce when they've been hit or when they fall below a variable health percentage (you configure these).
When they do, they give a message.
Mine is, "Vysha hit, Press G1." Or, "Tessa hit, Press G2".
G1 and G2 are G-Keys on my G15 keyboard, which just press a keybind, with my wow heal on that keybind.



You can also go with your healer assisting your tank/active toon.
If your macro read something to this effect:

#show Healing Wave
/Assist Tank (Choose your assist method)
/cast [help] Healing Wave; [target=targettarget, help] Healing Wave; [target=targettargettarget, help] Healing Wave

So we have your Resto shaman press this key.
The Resto assists your tank, so she is now targeting whatever the tank is targeting.
If that target is friendly, the Healing Wave goes there.
Therefore, your tank can target an Elemental who needs heals, and your Resto heals them by pressing this macro.
If the target of your tank is hostile, then the first condition fails.

Which means the macro tries to heal the target of the target.
Let's say your Tank is targeting a boss. The boss is usually attacking the tank.
Pressing the macro now will direct the heal to the tank.
If your mage accidently over nukes and takes threat from the tank...
Then the bosses target is the mage, and Healing Wave hits the mage.

The third condition will generally only apply in pvp.
Your Resto assists the tank, who is targeting an evil Undead Priest about to commit attrocious deeds.
The Undead is hostile, so it goes to their target, but they are healing a Blood Elf rogue.
The Blood Elf is however attacking a stalwart human ally, so the heal goes there.




A third option would be a lot of modifiers in your macro.

Let's say you have Tank, Mage, Elem, Rogue and Resto.
Your macro could read:

#show Healing Wave
/cast [nomod, target=Tank] Healing Wave
/cast [mod:alt, nomod:ctrl,shift, target=Mage] Healing Wave
/cast [mod:shift, nomod:alt,ctrl, target=Elem] Healing Wave
/cast [mod:ctrl, nomod:alt,shift, target=Rogue] Healing Wave
/cast [mod:alt,ctrl, nomod:shift, target=player] Healing Wave

Pressing this macro heals your tank.
But if a modifier key is used, it will not heal the tank.
Depending on the combination of modifiers used and not used, which has to be exact, it goes to someone else.
Just make sure the modifiers do not overlap; [mod:alt] for one, and [mod:alt,ctrl] for another will confuse the macro when ctrl and alt are both pressed, whichever of the two conditions is listed first will apply, with the other not getting heals.
