How about custom camo. You design it in an emblem sized window, and it is applied all over your gun? Sounds like fun to me!
Ehhhhhhhhh... I don't want a bunch of dongs and swastikas all over my screen while I'm playing. I can ignore them when idiots use them as emblems, but I don't want to have to look at them the entire time I'm playing every time I play.
