i use it for assassinations on my warrior.
can't identify werewolves>_>
Actually, except for eliminating a certain traveler on the road for the DB, people have recognized me after I've killed people as a werewolf. They say things like "Gods strike you down," or "Something I can get for you, you miserable wretch?"
A hidden fury spell or a frenzy poison is great for making people attack you, so you don't get a bounty.
On topic, I've mostly used werewolf transformations to travel quickly at night.
