@Paul You create a weakness for the heros. Superman i.e. Kryptonite and Teen Wolf werewolves - wolfsbane. I could see their healing being absolute regardless of the wound (minus decaptation) unless they are exposed to wolfsbane. Therefore healing is slowed or non existent leaving them open for lethal attacks.
