This fight isn't too bad. It's a very rare comp.

Pull your Felhunter out for this fight. Keep CoEx/FS on the Rogue as much as possible (alternating whenever needed - mostly it should just be CoEx, as needing to Frost Shock the Rogue in this comp is rare.) Purge Blessing of Freedom straight away. Purge other buffs. You can either DPS the Rogue, with a Tongues/Earth Shock/Spell Lock/Earth Shock rotation on the Paladin or drain the Paladin. Whichever you want, they all work for us, one's just slower than the other.

Obvious tips:

• Don't let the pet die, Earth Shield on your Warlock, Water Shield on you.
• Warlock Perspective: Keep tongues up on the Pally at all times. Between ES and Spell Lock, he shouldn't be able to cast much at all outside of his bubble. It's not a terribly difficult comp to beat, so long as your Shaman keeps you topped off, as a blind will be enough to kill you if it's followed by a Vanish/Sap or a Hammer that you can't remove (which you should be saving your dispel for anyway). Mana draining the Paladin isn't that viable vs. a rogue, since they're pretty much a tank, a powerful DPS, and a CC on their target all at the same time.
