Regarding Feral Vitality: I've seen a thread where people were discussing a possible feat granting fast healing. There was a common opinion that the fast healing should scale, which Feral Vitality doesn't. I can understand the scaling because the more hp overall you have and the more damage you can receive, the less impact this feat has during a battle. It seems off to me that a 20th level character benefits less than at level 1 from Feral Vitality. So is this restriction deliberate?
