I'm wondering if I should. And how would it benefit me? Especially on higher levels. Thanks.

Yes indeed I suggest you become a vampire, now which vampire we talking here? The regular vampire or the other vampire?

I have all the dlc. So whatever works best.

Well if you chose ot there is benefit's with the vampires. You get perks and etc you know I think its a great idea to become a vampire im one on my character.

What bothers me is the damage in sunlight.

Yea well that's why you should play the dlc and see what you can do to prevent that. =)
