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.
