Attempt to take out the Warrior on the Rush. Bloodlust+Lightning Bolt+Chain Lightning+Earth Shock should finish him off. If by chance it doesnt, PURGE PURGE PURGE. After you have debuffed him heal up and find your next target. Purge away again. Realize that against two healers you really need to change targets a lot if your not using focus. The healer just keep your main targetted and find out where the DPS is going and front load it. Purging a target allows you to soften them up, lower they're DPS, and make the healers anticipate damage your not going to give. Then switch targets real quick and drop em. If they get heals go back to the purged target = gg.

Also if you dont get the Warrior down on the Rush, make sure you pallie is dropping BoP on your main. This will void a huge amount of dmg the warriors and hunters are dropping on him. In that time though, you have to drop a DPS target. Me and my pally call it the double bubble win. He bubbles me, Bubbles for the heals...and hopefully we've killed 2 or 3 before the bubble pops. Works great.
