I'm making a blizz sorc right now pretty much for that reason. I was thinking about making a barb, and seeing how many total auras I can have w/ the aid of a merc(Doom,Dream,Bramble,Beast/Pheonix-switch, Merc-Infinity maybe Pride,Dragon ) that would be tight. But I was going to make a blizz sorc neways so I'll go that route for now.
