Yeah, but my dream of aristocratic, openly oppressive, decadent vampire arabs....
But seriously, are those the only options of becoming a vampire? Either asking your liege or seducing a vampire and hope for the best?
To be fair, A. most people don't really want to become soulless abominations of unlife for reals, and B. if they truly want to, they'll submit to a Vampire the instant they see them.
Also, Vampires should be fairly cautious about not creating more rivals over the food.
