Sunwalker [ Paladin ]

The Sunwalker transmog, made of primarily PvP gear, is another one of my favorites.  The burnished bronze look, along with the glowing white/blue accents on the shoulders, belt, and gauntlets, adds to a simplified effect accented by the realitive plainness of the pants and chest.

Attaining this transmog means you are going to have to enter some random battlegrounds (and win) to attain the Marks of Honor needed for the main parts of this outfit.  Additionally, some items may be found on the Auction House or by playing around in Ice Crown Citadel.  For the pants its a bit easier as you should have already done the quest and it should be waiting for you in your transmogrification panel...if not, get down to Pandaria and do the opening quest for it.
