Ever since Transmog (short for Transmogrification) was added to World of Warcraft back during Cataclysm, players have been able to express their creativity. No longer is their fashion at the mercy of whatever loot they've acquired so far or what has the better stats. A visually unappealing sword can be made to look like a much more satisfying weapon. If World of Warcraft players don't like the way their class armor set looks, they can simply use a different appearance.
