If we can't have more essential things, like storage space, due to technical limitation, why do you think we can have this amount of character customization?

The amount of data that needs to be stored and backups as well... Not to mention the loading times for slower internet would be increased and the amount of work to put into molding gear into each body type.... Imagine if you're a fat Hyur or a very busty Female Roe, the stretch of clothes on your gear would be noticeable and they have to fix that....

If I want a more detailed character customization, I just want the feature to customize my face. The eyebrows, my eyes, my hair, my nose, my mouth and jawlines... that sort of thing. It will not impact gear but still offer customization. If I get a penny for every time I see a twin face such as me, I would get about three fiddy.

tl;dr Don't give body customization. Give face customization.
