I wish we could edit and create our own helmets or hats. A nice 10 gallon hat would look superb on my viking's noggin.
Yes, it would be nice. However, I'm guessing it would be very CPU intensive to load all the hats (I might be wrong) and it shatters part of EMC's vanillaness.
Actually not, it would just load like 10% more of the skin, which is something that does the client and not the server. Still, this will never happen for a single reason: EMC is too squared for that.
