I'm of the opinion that you can be flexible on the powers/abilities of a vampire in order to fit the vampire into the narrative you're creating. If an element of the myth doesn't work for your storyline, chuck it.

Pretty much this. 

As a sidenote; vampires are something people can get super pissy about because Twilight, but ironically nobody cares what you do with something like the Lamia. Which I made a sentient race with great aptitude for spellcasting living next to humans at one point and everybody loved it. It's all about how popular something is, I guess.
