A huge identifier for Werewolves in this world is their need to kill. Unlike Vampires, Werewolves must kill on a nightly/monthly basis in order to survive. In case you ever wandered, THIS is why Werewolves are feared and hated. Prince Hircine's Sphere is the Hunt and his children reflect this admirably by hunting at night and being hunted during the day. This is, arguably/theoretically, why there are forced/involuntary transformations during the full moons, Hircine demands the hunt and thus those that refuse simply perish. Aela the Huntress perhaps stated better than I - "It means waking up every day knowing that you could die and having to earn your life by clawing for every breath.” This is what it means to be a child of Hircine.
Emphasis:
When it comes to Werewolf related conversations, the other Werebeast are never mentioned, save one book I know of, it's always "Werewolves". Yes, there are several different types of Werecreatures - Werebeast - Manbeast and Werewolves are not even the most numerous found in Skyrim, Werebears are. It is not that the opportunity to introduce or reintroduce a new Werebeast was missed, it is that they are completely absent in thought. Informed individuals such as the Silver Hand, Vigilants of Stendarr and actual Children of Hircine should know this.
Conclusion:
The Elder Scrolls’ unique take on Lycanthropy or more appropriately, Therianthropy is a well received respite from the over romanticized twilight/underworld/vampire diaries crap that is plaguing humanity. It should not be relegated to a two minute killing spree absent of substance and background but embraced and expanded upon. After Daggerfall and Morrowind, the Werebeast in Skyrim are just…meh. Bethesda, I implore you to fix this.
