In most cases, the werewolf form for me is still usable in certain situations, but at some very steep costs. The only reason I might think of using it these days is to save wasting charges on my enchanted weapons in regards to taking down weaker bandits. Even with my particularly mediocre equipment overall for my level, I can easily outperform in just about every situation. Overall, the werewolf form is lackluster from the many disadvantages it gives compared to the few strengths it grants.
