I don't know how it is for other races, but as a human, I can already change my hair style, hair color, facial hair, and face at the barber shop. So the only thing I actually can't change is skin color. And actually I really don't wanna pay 15 euros just to change that. That's like a month of gametime, just to change my skin color.
And you can already change your face, so "it's just a barber shop" isn't even an argument. Why not just throw skin color in there and remove this ridiculous cash grab from the shop?
