when I first played here they were free, I never made additional characters then, and I am definitely not going to buy 10,000 gold to do it now. I really don't see the point in any of it unless part of your fantasy is to have multiple characters with different characteristics. If that is true, then I see no harm in charging you for it. It's a way for 3dx to make money and well they are a business trying to make a profit.
So I think it is fine the way it is.
