Dragonflight Alpha is adjusting some aspects of character customization, renaming the traditional Male and Female options to Body 1 and Body 2, while datamined strings indicate that players may be able to select their preferred pronouns – choosing between he/him, she/her, or they/them – and voice!
The renamed options, as seen on the character creation screen.
The new body type labels are merely text changes within the character creation screen and barber shop.
