I didn't play as a werewolf yet, but from what I have read, you can change into werewolf for 2 minutes or so whenever you want, once per 24 hours. Ok if werewolves weren't introduced earlier in the series, I would probably accept that the game creators had a different vision on the werewolves, than the typical one.. But come on, I think that bloodmoon story was pretty focused on these beasts, how the curse works etc, so now this easy version seems a little stupid :< Reminds me of Twilight werewolves actually.
I would love a mod that make lycanthropy works like in bloodmoon, you can't choose when you transform and this form stays for a longer time.
