nomodifier = cast on target modifier = assist cast?

I've been trying to set it up so that I If hold assist my shamans heal the master's target and if I don't they heal their own target. The reason I'm doing this is I change my key bindings to F1= target party member 2 (leader) f2 = target self etc. Also if this was possible that would mean that in a raid setting I would be able to heal separate targets with all chars. Also If I have all chars healing the same target that's more heals hitting in one second than I really need on one target. I would like to spread out the heals If I can.

For example would It be possible to Have shaman 1+2 heal 1's target and 3+4 heal another target by doing something along the lines of
Alt+healkey for Shaman 1+2 and Shift+healkey for shaman 3+4
So I could target party/raid member X press alt+key then switch targets and press Shift+key rinse repeat. Also I Would be able to set up /stopcast macros similar to this to stop the casting of each individual char or all 4 at once

Any help/tips/ideas?
thanks

/cast [mod:shift,target=targettarget,help][help][target=player] Healing Wave

Make sure you put your cases in the order you want them evaluated so it will fall-through properly. Otherwise you have to add more explicit statements like nomod. This will (should) cast Healing Wave on your target's target (assisting) if you hold shift and that target is friendly, on your target if it's friendly, or on yourself if neither of those cases is true. (Sometimes multiple target= statements don't behave as expected to avoid letting macros be too "intelligent" but I think this should work.)

You can change the targettarget to party1target if you want it to explicitly be the leader's target, not a literal assist. I got a little confused after the first bit of the post.

Yea I wrote that in a food starved state of mind while I waited for dinner to be ready.
I'm using AHK(mostly because it's free) So I suppose If I wanted to do this the easiest way would be more keybindings, which sucks. It would involve having a genral assist key for all clones and each clon having seprate assist keys as well as each possible comination of clones for pvp safety.
So Lets say I wanted to heal raid member X with Mastermind and clone1 I would press assist key for clone one and after the heal starts casting i would target the person I want to heal with clone3+4 Press their assist key and then 3(my heal). Rinse and repeat? I suppose this could also be more easily managed by an addon which i'll request unless someone has another Idea.

I think this is probably something you'll need to play around with to get it working how you want it to.

What I'd suggest is the following:

ToonA -
/stopmacro [mod:ctrl]
/cast [mod:shift,help][target=mouseover,help][target=player] Healing Wave (leave out the mouseover if you want, that just gives you the option of healing someone other than your target from your main and you could put the mouseover bit before the [mod:shift] part if you want to be able to heal one target on toonb and one on toon a)

ToonB -
/stopmacro [mod:ctrl]
/cast [mod:shift,target=ToonA-target,help][help][target=player] Healing Wave

ToonC and ToonD -
/stopmacro [mod:shift]
/cast [mod:ctrl,target=ToonA-target,help][help][target=player] Healing Wave

I think (but am not certain) that if ToonA doesn't have a target then the macro will still continue to trying to cast on the toons target (if there is one) or themselves. Which means you could heal just 1+2 or just 3+4, potentially wastefull still, but not as much as everyone healing themselves everytime you press the key. If for some reason the macro doesn'tfall through you'll need to add in [mod:shift,help][mod:shift,target=player] after the [mod:shift,target=ToonA-target,help] part.

Along with these macros it would be a good idea to have a macro to select a target on each toon and one to clear a target on each toon. Possibly you could get this on pone button by using modifiers, but I'm not sure which way it would be most sensible to set that up. Also if you can append assisting/clearing target with a condition then it makes it somewhat easier. ToonA won't need a macro, as you can just select or deselect their target.

e.g.
ToonB -
/assist ToonA [mod:alt]

ToonC -
/assist ToonA [mod:shift]

And the same for cleartarget. If you can't add conditions to those then you'll need something more complicated, e.g.

ToonB -
/stopmacro [mod:shift][mod:ctrl]
/assist ToonA

ToonC -
/stopmacro [mod:alt][mod:ctrl]
/assist ToonA

This also has the down side that you can't select the same target on more than one alt at a time, whereas you could with the above method by holding shift and alt and pressing the key.
