But with jamba proc you can set it so each toon has their spam this key right for dps. Then if they proc they have their own button on th action bar they can spam while your spamming dps on the rest. You could do this for all.

I think I will be using Healbot for this with repeater regions.
When I need to force a particular spell to one of my toons, I will run a macro... I just need to find an efficient way to make sure that the spell gets cast.

What do you guys thing of this solution? Healbot for DPS. Only for the individual procs mind you.
