I don't understand why they would approve the design of the races knowing said design would, for whatever reason, be difficult to implement the hairstyles other races have gotten, or will get in the future. They had to have known this wouldn't sit well with their players since the vast majority of their player-base spends a great deal of time and money on cosmetics.

I'd really like to know how this effects hairstyles they add in the future, or if this is limited to old hairstyles. A lot of people paid actual money to race change to the Viera, which they knew would happen, and will have to pay real money again to change back to a different race that has access to the full selection of hairstyles.
