It does seem rather incongruous that in a game called about warcraft, changeable hairstyles and new dances would be a big deal, but it's true! This is something we've been wanting for a long time, but I never for the life of me imagined it would be an expansion feature. I always thought it would be like voice chat and guild banks, added in with some patch or another just like so many other things.
It begs some frightening questions: Are we going to have special hairstyles and dances only available to those who have bought the expansion? Will we have to quest for that really epic hairdo, or spend hours and hours grinding for the reputation to access that one faction haircut we want? After all, we do it for special mounts whose only claim to fame is looking cool, why not for hairdos too?
I suspect there won't be such thing as an epic hairdo quest, nor rep-grind barber shops, but really any which way Blizzard manages it will be fine with me. I do hope there will be new skin colors, faces and other characteristics be available too, though one could argue that should those be set in stone. Also, one would wonder if it's just new hair and dances which they have in store for us, or are there going to be a whole slew of new social features? Dare we hope for a proper /hug animation?
