I think most people already understand how Werewolves work but they've made some interesting upgrades to it. The Werewolf has a perk tree just like the Vampire Lord but instead of getting credit towards your perks for killing people with a certain attack, you get points by feeding on the dead.
The real beauty of the werewolf is in the perk tree though. On the right side are some interesting abilities, not the least of which is the ability to feed on almost anything that's flesh and not a dragon. If you go up the left side, you'll get the ability to summon help when you howl. At its highest level, it will actually summon other werewolves to help you.
Unfortunately, my experience with the Werewolf has been limited. It's fun to play and it's good that it's gotten stronger but I still prefer the Vampire Lord.
