I'm not trying to make Werewolf OP it just could use some small buff and tuning to make it viable.
1. The main issue I see with Werewolf is a bug that disables weapon passives from applying to them while in Werewolf form I don't know if this was intended but if I'm using a maul or maces I should receive my penetration bouns instead it goes away.
2. Most people would agree that when they transform into Werewolves they typically will put the ultimate on the front bar where they have the most damage benefits when they change, I would say minor resolve as a passive, and maybe minor protection should be added for a slight increase in survivability for them no matter if they choose to back or front bar the ultimate.
3. Finally, Hircine's Bounty allow this to heal 5 or 10 seconds after the burst like (Green Dragon Blood or Artic Wind).
