[@Wade Wilson] and that would  me like granting a werewolf the okay to shift because a wolf isn't a mythical form. Shifting can  but it is very rare, especially the longer it has been since the change to human form. And to change back once again nearly impossible. Think of it like trying to remember you name with amnesia. It would take some massive to bring it back and then to lose it all again even more. We're talking boss fight, best friend dying in your arms, watching you lover turned into a kabob for dinner by Hannibal Lector. Big. It is not  day to day.
