If the Khalt Changes are Unsuccessful:
If the Khalt changes prove to be unsuccessful, and many Khalt users initial reaction from those I've spoken with in the time since the patch went live feel they are just that: unsuccessful, my suggestion would be to drop the ghost damage and heal from the ability and have Absorb do just that, absorb the damage. Keep the bump in armor for seconds, and its stackability. This might not allow Khalt a free hit like Forsaken can manage, but would allow the class to be the tanky bruiser it is suggested to be, and also justify its inability to absorb guard breaks, as they would be an appropriate answer to someone who successfully Absorbs consecutive attacks.
