Its not really that efective. Besides most players will look at your stats to get a general idea of your skill not you skin.
It WILL work. You know why? People check stats to see who's good and who's not, right? That's what their mind tells them.
Once they're in the game, they remove all of that, and judge players by how they look, or how fast they kill. Now, you can't judge people for how fast they kill until you're killed by them, so people subconsciously just judge by looks.
Don't concentrate on the person or the appearance, but concentrate on killing your opponent, because who cares? A opponent is a opponent and I'm going to try and kill every one of them. Could be useful sometimes, but naaah ..
