I think they would like to some day improve character creation. From what I could tell there is a lot of hefty internal workings they have been compounding on over the years making it hard for something as simple as the Hotlander beard to be made an option for midlander men. Like it would be something where they address a very expensive (in terms of developer resources) problem, and suddenly things will become much easier and more modular. Probably some nightmare of spaghetti code like a lot of FFXIV.

Maybe when they release on PS5 and XBox systems the FFXIV team can sit on Mama Square-Enix's lap and ask for a budget to bring in some support dedicated to software renewal, and then we can have such luxuries as more control over character parameters like au ra horn customization or muscle definition as an option for more women. As it is right now, the way the game works and the scope of how much data they are allowed to define for character actors, expansion is difficult.
