Argonian- Specializes in Stealth-Illusion-Being a Thief/Assassin. From what I hear, being a vampire is annoying. To me, I feel like it would add more fun to the game so eventually after I get my skills up higher I'm going to do it. But does it fit my character?

Argonians get really cool fangs when they turn, plus your illusion spells get stronger, and you sneak better.

Yes that build goes very well with vampirism, and it isn't really too annoying. Feeding becomes like second nature after a little while.
