The Grand Melee - Quest - World of Warcraft

I have found a really easy way to do this myself, and thought I would share.

• First you get 3 stacks of Defend like the others have mentioned.
• The Valiant will start walking off the direction it was facing before you talked to it. Start pressing Charge immediately to hit it in the back! XD
• The instant you Charge start pressing Shield-Breaker. You can hit them with this ability almost instantly, since your mount will be running a quick circle to face your target. They should now only have 0 shields up right at the start of the fight before they even touch you!
• Now just stand on top of of the Valiant and keep using the Thrust ability, and keep your Defend stacked to 3.
• When the Valiant starts to walk away start spamming Charge followed up with the Shield-Breaker like mentioned above. You should be able to kill the Valiant within 30-45 seconds this way.
