The idea is you only get sustain from being in combat. This means you can't sustain passively. Currently you can take damage and heal and keep fighting or be hit really hard and retread then heal and come back. now if you get to a dangerous level staying could result in an easy death since you can't just heal your self unless you are attacking something.
