ESO Head has posted what appear to be the http://esohead.com/skills?line=51, http://esohead.com/skills?line=50 and esohead.com/races/10-imperial skill lines.

If these hold up, What do you think?

Aren't they missing ultimate abilities for all the racial trees? Or am I insane?

Bats? Mist form? I'm disappointed vampires sound so...conventional. I expected an Elder Scrolls game would take them in a different direction.

I don't see them either but thought it's just me.

Checking out the skill calculator now to see if these guys are in there....

MIdnight Drain sounds interesting...the night thing is a cool twist.

I'm interested to hear what the disadvantages will be, so that we don't end up with a world of werewolves and vampires.

Fighters guild, they have skill lines that make them great to fight against both vampires (undead) and werewolves.

Another site listed some of the drawbacks (mainly vampires, but I assume werewolves are limited in terms of how often they can transform). Vampires are weak to fire, and for every time-interval (I want to say 6 hours) they don't feed, their health regen takes a significant hit.
