I'm sure some people who make their characters are good with it now, but then through much time, they begin to dislike what they first picked. Preferences or tastes change or maybe you're just tired of looking at the same thing. Aside from making a new character to fix the problem, why not try the Appearance potion?
The Appearance potion is basically just an elixir you buy from the crown shop that will change your facial features. For example, let's say you got the dark, menacing look with the white eyes. You begin to dislike it, however you are already a pretty high level and you don't feel like making a new character just to change a simple feature. So why not buy the potion, say 300-500 crowns, to change it from that menacing look to the relaxed green eyed look. Something simple you know?
