my only real annoyance is no 1st person view. there is no good reason for this. it's just a 'fuck you' to the player.
other than that, I have some ideas on immersion. there should be a "bloodlust" trait, where there is a small chance you lose control during battle and transform. every time you give in to your bloodlust, your werewolf is in 'berserk mode' for a period of time (let's say 30 seconds). during this time, you have no control of your character. an aggressive AI takes over that is hostile to everything. your speed and damage are doubled, all your attacks ragdoll, and your stamina cannot be drained. but a berserking werewolf neglects defense, so you take 50% more damage.
it's one of those "gamble" moments. your character could wake up on a pile of torn and shredded enemies, or find out, to his distress, that he mauled his companions to death, or just get killed like the rabid dog he is.
