Over my years of playing Wizard101, I have noticed the same faces over and over again which happens because there are only a select amount of faces you are able to choose from when creating your wizard.
I would love it KI could add more faces to the game, I think it would make characters more unique since most players have the same face. If KI added new faces to the game, I think it could definitely attract more people or maybe older players because of the new faces.
