Rage on hit support not working

1 rage gain on hit on tree / rage III support gem linked on mace strike results in giving me 6 rage on 1 hit.
But if i add armour break III Support+rage III Support i only get 1 rage on melee hit. theres a bug with armour break support i think.

further testing , it works on bosses correctly gives me 6 rage on it. It seems if i break armour fully on the first hit , rage on hit doesnt work correctly

From my testing, armor break doesn't count as hitting with the skill itself and uses the generic "+1 rage". This puts rage gain on cooldown and results in the rage support doing nothing.

I am unsure if this is intended.

Okay another test, removed 1 rage on hit on tree, now it gives me 5 rage on it and works correctly.
so first armour break,and tree rage on hit source both makes it buggy. all the info i got. hope ggg fixes it.
