Shouldn't the Witch hunter's little ascendancy nodes get a rework?

The small node for Culling Strike and Decimating Strike deals 35% increased damage to low-life enemies. The node itself has an expected value of 12% global increased damage, but Culling Strike directly reduces the damage expectation of this node. Against normal monsters, you get no damage bonus from it at all. If you stack your culling threshold above 100%, magic monsters won't receive the damage bonus either. I think it should be changed to provide a damage bonus against non-low-life and full-life enemies instead.
