Werewolfs and vampires are hunted pretty thoroughly by most races. Which makes having a pack hard, or a vampire covern. They are mostly hidden away in the dark corners of the world.
Which would make playing them hard, but that's part of the fun in my opinion.
I'll add in that vampires can hide all of their vampiric features when they're not directly in sunlight and they'll show more and more the longer it has been since they fed.
The sun and how often they have to feed are way more important for a new vampire than an ancient one.
A truly ancient vampire can go years between feedings and just feel slightly annoyed by the sun while a new needs to feed every day and the sun burns the skin.
