It's been suggested I might 5 man a Paladin, Shadow Priest, Holy/Disc Priest, Warlock and Mage.

As I already have a high level mage and mid level priest, I can started three together and meet them at their levels.

If I have Shadow Priest, Warlock and Mage - how difficult are macro's going to be? Lets say I had shadow bolt, mind blast and frost/fire bolt firing on one key.... or then maybe I should use mind flay instead - just concerned about the cooldown of mindblast.

Anyone run with a similar config got some tips?
