The thing that really bothered me while playing on beta was that every single worgen female I came across looked exactly the same to me. The only thing that separated one from the other was their fur color.
I am still clinging to the last (and possibly futile) vestiges of hope that they will add more customization to the model. I've been dying to race change my human rogue into a worgen for ages, but if they don't add any customization beyond snarlface and bedroom eyes, I might end up going night elf or gnome... sigh.
