WOW Quest:The Grand Melee (13745)  

Guaranteed way to win (assuming no disconnects or unforeseen glitches)

First off, forget the combo training you did, the comp is often faster cause of ping. Its very unreliable and often just gets you killed.

• Start the fight with 3 stacks of Defense
• Melee him till he moves to range
• Charge his rear
• Melee till he moves to range again
• Repeat till victory

Only refresh defense while in melee range, as it shares a cooldown with your ranged attacks, but not your melee. If its on CD when he moves to range, you will very likely lose.
