I probably went through about 20 different outfits for this particular round, and I had the hardest time landing on a race. By the time I finally decided what I was going to submit I ended up with a brief description of the character looking something like this:
"I figured goblin suited you because they seem a little shifty to me (something shifty only seemed to fit given the evil nature of this round). So anyway I figured being pretty much the king of transmog contests that your npc should be dressed good, so I totally pimped him out. This goblin is stylin’ and ready to judge some outfits! Oh, and to add a little bit of badassness to the look (cause we all know your a little badass) I threw in some brass knuckles so nobody would mess with ya!"
