Exalted Champion of Thunder Bluff

I'm sure with a title like this you can strike fear into the hearts of millions.

These champion achievements aren't entirely obvious.

(1) In the main building, you need to complete the "The Valiant's Charge" for the particular faction. This will require 25 Valiant Seals. You can get these by doing the dailies @ The Argent Tournament Grounds.

(2) You will then get "The Valiant's Challenge".

(3) Find Squire Danny (68,20):
[npc=33518]
*NOTE* - You must be on a jousting mount with the lance in slot. Otherwise Squire Danny will not give you the chance to fight.
(4) Argent Champion shows up and talks to Squire Danny.
(5) Battle Begins.
(6) Immediately "Charge" (3) champion. Activate "Defend" (4). Then keep at a distance and click "Shield Breaker" (2). I do the latter by just running away at an angle. Any time the Champion is at a distance, activate "Charge" (3) again. It's a very easy fight if you do this.
(7) Return to main building to cash in quest to get the achievement.

Note - This achievement takes a while because of the 25 Valiant Seals needed.

This does carry forward to the other faction
