A large reason for this in the past was due to the state of armor assets. The pipeline for getting all the armor graphics skinned to the female model is additional work after the male versions are completed, and all of the male armor concepts were implemented prior to the artists starting mass re-skinning.
That means that, until recently, there wasn't much to show on the female. While I'm sure many of the community would be more than happy with this fact for various secondary reasons, it didn't make much sense to show it from a polish standpoint.
This is more or less a non-issue now, so I'm sure it will start appearing more often in the future.
Une raison pour laquelle les modèles féminins n'étaient pas exposés jusqu'ici dans AoC est parce qu'ils attendaient de finir les modèles masculins pour commencer à skinner (habiller graphiquement) les femmes. D'après Jayde, on devrait en voir plus souvent à partir de maintenant.
