Mages at CWKPQ?

As an I/L spamming CL gives me more dps then spamming blizz. Probably cause it hits 3 targets unlike paralyze which only hits 1. I only blizz when the small mobs get summoned. And when you're spamming your ultimate you can't move, so you have a chance to get knocked away and get stunned.
Also with slow, the bottom 3 are easily controlled. KBing the warrior boss is a bit of a pain, but he's so slow you can just lure him in lol.
