100% disease resistance is granted to werewolfs, vampirism is a disease :(
Still you can just add the perks manually with hax later, i assume theres a mechanic to block it the other way as well otherwise a vampire>werewolf switch seems to be doable.
Werewolf is perfect for those situations when you're trapped, fall back a little, activate the power and bitchslap everyone and feast on their corpse.
Only downside seems to be you can never get the well rested bonus from sleeping, a small price to pay.
I never thought they'd do it. This is so catastrophically awesome.
Assuming vampires don't sparkle in this game. :P
how to be a Werewolf?

wow!!!!!!!!!i can't wait!!! nice video!
i think that i have to try this!!!! wauuuuuuuuuuuuuuuuuuu!!!
Well you can be both werewolf and vampire the ring of Hircine is in the game so get vampire-ism and do his quest btw I found a glitch to get both his items ask me and ill tell you
Do you revert to and from Werewolf form or are you it permanently?
