It always bugs me whenever men that transform into creatures other than werewolves are referred to as lycanthropes. By definition, a lycanthrope (derived from Greek) is a wolf man. The overarching term for all sorts of werecreatures would be therianthrope.
On an aside, the myth regarding Sheogorath and Hircine also rubbed me the wrong way... how is giving a Daedroth the ability to transform into a werewolf going to make it any deadlier than it is? Regardless of the race they begin as, they all end up the same after transformation.
