duh, i have forgotten about arcane mages' slow. With multi target sheep and slow, your team is definitely looking good.

Arcane mages are all about controllable burst. It is somewhat like shaman, but more OP lol, since the main spells are instant for burst. I think if you can land that sheep (let them trinket). It is pretty much over for them. Just make sure you cc or burst them down before they CC your priest to fuck up your target assisting (this is driving me nuts by the way, main gets blinded, slaves can't assist. Even after my main wakes up, slaves still have their target stuck. I have to do a leader switch to solve this.)
