The main problem I have with werewolf is that feed function it doesn't work that well. There is a delay that causes lot down time to and it takes awhile to get through the animation. But the heal is small where you can die trying to feed. But unlike vamp makes you almost un-killable for how much life you receive.
I think they should allow you feed on live enemy and it either do damage or pure heal. If they do this then I think feeding would be less glitchy especially trying to give someone the bite to become werewolf.
Or they can just lower the ult to 100 so they dont need to depend on feed mechanic at all.
