I understand that the eating brains part isn't practical too. I mean how they gonna crack open your skull to reach them? Only by brute force and slamming your head against the wall or floor and even so I guess it wouldn't be that easy, but they can still feed on the flesh of the living
*edit* but in my case I think it would be more practical because they would retain some knowledge on how to use instruments.
Thanks for your opinions so far, if more people want to hop in I would appreciate
By the way I normally don't mind changes on creatures, but sparkly vampires are just too ridiculous. What? Did they mated with ponies or something? And they're so emotional and sensitive. Oh well, better not talk about it
