The spell is fair enough, I play warrior so I was only basing my assertion on that background, but your reasoning behind skipping werewolf because you need to spam roar is just fail. To survive as a dual-wielder you have to spam attack, to survive as a destruction mage you have to spam magic, to survive as an archer you need to spam arrows; I guess there's a lot in this game you're not prepared to do.. not to mention the fact you don't actually need to spam roar, as it lasts for like 30 seconds. You only need to roar again in the meantime to cancel the feeding animation or hit foes you didn't hit with the first one.
"The spell is fair enough" Wonderful, so you admit that the werewolf form is completely and utterly useless to me and, indeed anyone who has a good range of powers, spells and shouts (which should be most people late in the game). As for the rest of the comment - not only did it completely miss the point, but you made it clear that you have no intention to be polite - and thus I wont reply to you any further.
