The main strategy is to train the Priest until he is dead while CCing the Paladin or Train the Priest until the Paladin bubbles then quickly switch and down the Paladin. Both are viable and work well.

Place you Felhunter on auto devour. Put your pet on their Priest. The Warrior should stick on the Priest and should be sundering 2-4 times depending on your target's armor and your Warrior's armor penetration. The Warrior should be in charge of pummeling Mana Burns.

The Druid should be controlling their Warrior as much as possible with Roots and Cyclone. When the Warrior is on diminishing returns and can no longer be CCed you should coordinate a Cyclone on the main healer (Paladin) and coordinate Fears with the Warlock.

Warlock should be keeping 3 DoTs on the Priest. 2 DoTs and Curse of Tongues on the Paladin. Curse of Weakness on the Warrior. The Warlock should Spell Lock early to get the Paladin to move to Holy Lights instead of Flashes. Fears and Tongues will force him to move to larger heals as well. You should primarily be Fearing the Paladin and a Fear on the Warrior every now and then when he is on Cyclone DR. This should be able to put a lot of pressure on the other team. It will either force a Blessing of Protection, a Pain Suppression, or a Paladin bubble. All of which are good! The earlier the better. Once the Paladin bubbles he is now viable to train. You have Spell Lock, Pummel, and Feral Charge which should easily lock the Paladin down while you go for the kill.
