Well, in Skyrim the werewolf had a base duration of somewhere around 2 minutes, but eating the corpse of an enemy added on 30 seconds, I think it was?

Will the Online mechanics be the same? No idea - that said, since it will have its own trait tree, chances are it'll be a bit more than a flavor-feature; perhaps there'll even be a trait to make it permanent?
