I've finished dawnguard quest from both vamp and dawnguard side which pre much get the same ending nnyway ^.^ but while im playing through the dlc as a werewolf. Throughout the story line the vampires people like Harkon and Valerica(or whatever the hello her name is

) treats me as if Im some MORTAL guy.... I mean i know that they're vampires so they'll live forever unless i put an arrow through their face. But Isnt that the same with werewolf too?? I mean arent both vampires AND werewolf supposed to have that longevity?? living forever unless someone kills you?? or something like that?
