Simple, you cure your lycanthropy, you are F-d in the A. Harsh, but it was your choice after all.

After taking a good look at the video with Matt Carafano talking during E3, i couldn't help but notice that the Werewolf was taking rather large amounts of damage from getting shot by that guard's bow, and it wasn't even a crossbow. This leads me to believe that Werewolves will not be getting a Armor Rating upgrade. Which means Werewolves will still be "squishy", which svcks.
Prior to Patch 1.3, the Light Armor skill and the first perk in it, Agile Defender, attributed to your Armor Rating while in Beast Form, but Patch 1.3 glitched it and gave Werewolves 0 Base Armor Rating.
Like i said before, my Nord Warrior has a base Health of 550, and 650 Health in Beast Form, but he can still be killed in like 3-5 hits from a Draugr Death Overlord in Beast Form, when i can take on multiple Draugr Death Overlords without a problem when in Human Form. So simply pumping up the amount of Health that Werewolves have (Like the Animal Vigor perk does) is not the answer to making Werewolves less "squishy". One thing that i do find that helps me survive fights as a Werewolf, is right before i transform, i drink a Elixir of Regeneration that increases my Health Regen by 100% for 5 mins.
