Some players are asking about updating the older models in the game to reflect the updated style evidenced in the newer content. Anyone who's run Old Hillsbrad can see exactly how far we've come from the WoW original models, and some would like to be able to have new choices as we progress into WotLK. Drysc reminds us, though, that some people are very attached to their character's physical appearance. Some players have been with those characters since 2004. To change their faces would be like giving a friend plastic surgery. Or what about body types? Would you feel that you were playing the same character if there was suddenly a major change to their physique?
Personally, I am eager for the hairstyle changes coming in the expansion. I don't feel like my character needs a new face perse, but the difference between a Blood Elf or Draenei hairstyle and a human one is pretty drastic. I actually considered rerolling my main character because the new races just look a whole lot cooler than she does. Faces though, I'm not sure. How would you react if Blizz changed the models, or gave you more choices?
