I think people need to understand, most people play mmorpgs as simply games not as a medium for them to roleplay on. So everything doesn't have to make sense, its a matter of pleasing the customer. If you are a good roleplayer, you can make sense out of non-sense lol.

By the way I like rping but my personal opinion is I think vanity slots actually help in roleplaying, as it allows a person to roleplay what they want and how they want it to be. More freedom.
