also remember that when you mouseover someone, it only works on the screen you're mousing over. your slaves will not see your mouse pointer on your main. they will not be able to know who your main is mousing over or mouseovering, or whatever.

your macro doesnt work because if you cant do the renew, you will not go to the next spell. so your conditions might have to be a bit different.

/castsquence [target=mouseover, help] [target=targettarget, help] [help] [target=player] Renew, Heal

1. checks for mouseover helpful, yes? renew, heal. no? go to 2.
2. checks for targettarget helpful, yes? renew, heal. no? go to 3.
3. checks to see if the character's individual target is helpful, yes? nenew, heal. no? go to 4.
4. cast renew on yourself. cant cast heal. why? because your macro basically rules out renew except to do it on yourself, why should heal work... unless on yourself?
and remember, if your renew does land, your heal will always go to the slave's current target, since you have it only to Heal with no conditions. So, if your main is targeting a level 70 mage and your slaves are targeting you, your renews will probably land on the mage while your heals will only land on your main.


also, another reason your macro doesnt work is because, if your slaves are targeting the main, the first condition will always be true, therefore, it will cast renew always on the main. always. in your macro, you made [help] the first condition. so your slaves will evaluate that their target (the main) is helpful, and will cast renew on the main, then heal on the current target, which is also the main. see the problem?
