You know... actualy be able to howl now... as in... the http://www.youtube.com/watch?v=iag8d1ENKgk sound... not the weird ass distorted tigre growl that it is now...
I want my werewolf to recreate the No More Tears music video while singing Bark At the Moon. The werewolf has to look seductive in order for this to work. And the lady werewolf has to drown for realz.
Howling at a full moon at a designated period of night should give you additional werewolf bonuses - as a reward for immersion; maybe increased running speed or being able to call a pack of wolves to help you in combat.
Well, according to the GI article, one of the new Werewolf powers is howling to summon additional Werewolf support. I'm going to assume they'll do your usual stereotypical howl at the moon.
