The entire problem with the character creator presently, is that it evolved from V1.0's

The game engine is capable of more (see FFXV) but the more complexity you let it do, the less you get. That's why you can make 100 different sliders for the face, but the shape of the head never changes (even the shape of the jaw never moves that much), so all gear still fits.

When you start adding sliders for customizing the length or girth of things like ears, horns, hair, arms, legs, gear will start looking wrong, and thus we get less of it. It would not be out of the question to make race-specific gear if we wanted that additional customization, but I think more people would rather ALL gear be available for all races, and genders, and not have the limitations of other MMO's that lock gear to race/gender/job.

What I'd like to see is some body "girth" type of slider to at least make characters more lean, muscular, or more fat, because that's one of the bizarre things about characters in FFXIV. Everyone is super-fit, except for male Roe's and Lalafells. Male Roe's just look bulky, while lalafells lack any body definition at all (both male and female lalafells may as well be the same body model.)
