I've it set up with a button (clickbar) on my warrior. So i just target a mob i want to sheep, dubble click the button and mage1 start casting sheep on it. And its a round robin so i can just keep target mobs and hit it and next mage will sheep (Got 3 mages). Found this way very easy and fast to manage my cc's

I'll try get a vid up on my set up as soon as got time over
