Ancestral bond + non-totem skills + Life Gain On Hit

I have a character with Ancestral bond, explosive arrow totems, and frenzy as a utility/charge generation attack.

The Frenzy skill is doing zero damage, exactly as it should, but my problem is that when I link Life Gain On Hit Support to frenzy, I am recovering zero life when I hit monsters with the skill. With GMP and Chain support firing into a pack I should easily be getting 400-800 life per shot, but I am getting zero per shot.

When I read all of the relevant gems/keystones I don't see any interaction that should disable gaining life for each hit from the Frenzy skill, and yet it does not work.

The character is Carly_Marks_Gramma in my profile.

If your profile is up to date I see frenzy linked with lifetap support but no life gain on hit support.

Yes, I removed it because it wasn't doing anything.
