You can't "lock" something that doesn't exist.

I just hope that when male Viera/fem Hrothgar are inevitably added to the game, SE activates their trap card and reveals some wild, crazy models that no one expected. Nothing close to the concept art. Then we'll see if the real reason people are fighting for this is for gender opportunities/RP or just cosmetics.

I truly believe most people will just be thrilled to have them playable!
