Why? Because in the newest book in the Dungeons and Dragons 4E line that is coming out from Wizards of the Coast not only seems to be built for the Essentials line, ignoring the original 4E line, but one of the newest classes available in the Heroes of Shadow is the Vampire.
"Now, wait just a minute" you may say. "This makes very little sense." I agree. However, if you are just as confused as this hypothetical person commenting on the class choice, check out Wizard's excuses HERE. Still not agreeing with the choice? Allow me to help you with that.
You see, long ago in distant Pre-Essentials era, there was a little thing that WotC introduced, and then promptly ignored, called Themes. Themes were introduced in the Dark Sun Campaign Guide and were meant to be the third branch in creating a unique character, something the Backgrounds introduced in Player's Handbook II didn't seem to be accomplishing for them. Each character would have a Race, a Class, and a Theme so that, for example you, could be a Halfling Wizard Gladiator. Interesting concept, yes?
WotC, we need to talk. Why couldn't Vampire just be a Theme?
Why can't I have a Dragonborn Paladin that is also a Vampire? Or, if looking at Essentials, a Drow Hexblade Vampire? (I am aware that the Essentials doesn't have Themes yet, but it is worth testing)

As you can see, the Vampire would work wonderfully as a Theme. Of course, I drew inspiration from the article as I'm not going to entirely discount the hard work and enjoyable designs of the WotC crew. I'm pretty sure these powers here also need some balancing.
I also think there should be a second Theme, Vampire Lord, that is a Controller type. If there is enough demand, I'll finish this Theme and maybe do that one too.
