I want them to look like wolves. I want them to be able to walk on their haunches, or on all fours. Full fur, head to tail. Pointy ears, and canine teeth. To have a muzzle, not just be a remake of the TS3 hairy humans. I would love to see the option for a werewolf to go feral and change into wolf form and stay that way until the player chooses to make them human again, a permanent wolf state. An option to form a pack, not just a club made up of werewolves. A clear pack leader who has to earn the spot and must maintain it. I'll think of more later I'm sure.
