I am at work but i have an awesome mage sheeping macro. Ill post it when i get home.

Basicaly its F2 sets a raid icon (Skull) for main and Sets a Focus for main as well
F3 Sets a raid Icon (Square) from main and alt 2 sets focus
F4 Sets raid icon..... you see where im going with this.

Then I just target one hit F2, tab Hit F3 and so on untill i have all the CC targets marked and set as focus. Then i have a CC Focus key on all toons. It just does a target=focus /cast CC and i put in there a stop macro part and an announcement. So the macro will stop if there is not focus target for that clone and wont announce the CC on target.

I hope this gives you a good enough idea. I use it on my hunters as well. i have my main raid target, my alts set focus and cast Hunter's Mark (that way i know lag didnt mess up the focus). then i have a pet attack focus macro so i have 4 piggies charge 4 targets... its great

So given enough time in an arena to set these up hexing would be HAX :P
