Personally for me I want the werewolves to be able to hunt in small packs which you would be able to do with a call of the wild howl that brings nearby werewolves out of hiding to aid you. And if your in a city and use it have people who are hiding their lycanthropy transform and fight with you. Other than that for wolves have them become vastly stronger during a full moon or put in a blue moon cycle where they beef up. Also different color werewolves like a silver haired one would be cool.
For VL's I like them a bit but I dislike their appearance because they look like a rip off of the vampire in underworld 2. Also more ferocity in their melee combat form like a wing hitting a person in their chest and sending them hurtling in a finisher would look awesome.
All in all I love both forms but their is a lot more they could have done to these beasts to make them a permanent character role for players.
