-No longer a casted spell, you become a werewolf at sunset
-You must feed at least 1 time durring the nite or your stats will be depleted come morning (until you feed)
-Werewolfs are given the ability to smell blood, allowing you to see nearby humans

Anything else? Inputs!

I haven't played werewolf yet, however these ideas sound like they'd be fun.

Get active Silver hand, and Stendarr hunters on you by Hold if you are seen becoming or coming out of were wolf form

and well in addition to the Op thats all I can see would be nice ;p

I want something as cheap as a toggle able werewolf beast form.
Meaning I can change whenever I want back and turn it off at will.

Yes, I know cheap, but I want it as a fighting form, as for example entering a dungeon run by vamps and just massacre them all in werewolf form.
So much fun and it would feel like don't mess with me kind of thing.

Give me Underworld werewolf's, they look the part, now let me change at will and turn it off at will

Im sure you can already do that in Skyrim loki ;p

OT, the only werewolf mod I want is one that allows first person. I HATE third person with a passion and for a game that allows so much freedom, being forced into third person with something as AWESOME as werewolves I hate even more.
