Call me crazy, but I'd like it if the Aesthetician Bell allowed us to alter everything about our character's appearance outside of race, gender, and clan(also none of the nameday/star sign stuff).

And price it like SWTOR where the more things you change, the more expensive it is. So changing a hairstyle/colour might be 2000 gil, but changing your height, face shape, or skin colour might be 4k-5k gil.
