Also even without the claws of Hircine I just get the ring of regen to get health

Good stuff!

Could I go into speech

I could see a rationalization for speech. Intimidate being the tawny flash of your true eyes, or the danger in your wolfish grin. there is a certain "Allure" to being a werewolf too, "wolfish" and all that Red Ridinghood jazz.

Also why the left side of the enchanting tree

The build was a huge success but was to repetitive after the beast state became my main state so I reworked my old skyrim werewolf Paragon. Originally a joke character for being a small wood elf that could become a massive werewolf. This quickly become one of my top builds and was quickly nicknamed the ultimate hunter build as he plays a hunter/stealth archer with the added beast blood. Basically I rely on my signature sword dawnbreaker and my nord hero bow (Fitting since he was a companion). I only use iron arrows to add a more competitive aspect to the play through. I chose dawnbreaker by accident when I stumbled upon this strange beacon during one of his "Hunts". Now with the power to destroy the undead in his hands, Paragon joins the dawnguard to hunt the ultimate prey the Vampire Lord himself.

Vestigial. Left over from when certain weapon bugs worked with wolf form. I'll change it.

I always envisioned the wolf as a hunter in human form. Its seems to follow fairly logically. As for the fight against the Vampires, well I could see that too...
