Basically as the titles says, which class would be better?

Two-Hand Warrior, Heavy Armor, ETC

or

Assassin/Thief, Might Add Illiusion, don't care much for achemly.

May also do witchhunter, since I be joining DG.

P'S I know dg for pc has no release date yet.

If you're planning on joining the Dawnguard, why not add archery to the first build? Make use of those crossbows!

If you're planning on joining the vampires, I'd say a Mage build, perhaps a Battlemage. As I understand it, the Vampire abilities require magicka, so a large magicka pool is needed to get the most out of the Vampire Lord form.

Thanks for your reply and opinion, but I was looking for which class should I play out of the ones I had chosen. I know it comes down to me in the end ETC but I like to hear more opinions from others and I am open to other class suggestions like you did.

Any 'class' will do fine - unless you focus more on RP and things like: "I smithy, not Dragonborn!" kind of stuff. You won't do 'better' as a vampire by choosing any particular class - the vampire lord form in and of itself is outside the numbers of your skills.

With that said, I *prefer* to play as a necromancer, because it feels right to me to be a vampire and raise dead bodies like it's going out of style. Since I can't have living thralls (yet), I have dead ones. Satisfying

I'm happy with my own odd combination of Warrior, Healer and http://skyrim.nexusmods.com/images/113849.

Anything wearing light or heavy armor. There's only one good piece of non-armor in the add-on.
