Normally I would be all for this sort of thing in a game, and in many others I have spent alot of time collecting 'fashion' items..but I really dont see the point in 11. Some people like to know what others they have to work/deal with in game are actually wearing, and yes they can just /check them but, they're going to have to then check them again throughout fights if they want to know are they changing gear for ws, for spells, etc.

Most games I've seen with vanity slots, use completely different appearance, things made to look good, not just the appearance of an existing piece of armor. When it comes down to it, nobody is going to care what another person's character is going to look like beyond are they using decent gear or not (though they may want their own char to look nice). In that case, why dont you just swap your dats so you are wearing what you want.

That being said, even if it was possible to do this now I dont think it completely shouldnt ever happen. But if this sort of thing were to be implemented, I wouldnt even want it to be considered by the devs until we have more important things to do in game already aside from making our character tank something in what appears to be a swimsuit.
