Gender has been discussed before, many times. It’s too resource intensive to be a priority for the full launch of the game.
As for the other customization options, that feature always confuses me. Especially in a game like this, most of the common customizable features of a human(oid) character - things like hair, face, eyes, skin - are things you’re almost never going to see except on the character selection screen, just because of the camera angle alone, and once you factor in armor you’re even less likely to see it. I never understand why someone would want cosmetic customization in that scenario. Like, what gameplay experience do you get out of having a different hair style when it’s either covered up by a helmet, obscured by tons of visual effects, or otherwise just too far away from the camera to be visually distinct from any other hair style?
