I feel like this question could attract some negativity but that already come here anyways so… sorry 
Female beards on earthen are more than just a player customisation. Theyre a normal part of the race in tww with many female npcs using them.
Theyre just how the race normally looks.
If the customisation did get expanded beyond earthen, should the same apply to the races that get the options where its reflected in a large percentage of their npcs?
