I suggest:
  • Prot Pally
    Holy Priest
    3 warlocks


Warlocks can CC just as well as mage if not better. But they have the banish + enslave over the mage. Furthermore, with a paladin tanking, you dont necessarily even have to CC anymore if you buff up your paladin well enough.

PS
If your alliance, get a dwarf priest - fear can be a real pain.
