I would like to see calling EMS. I just have one thing to add, maybe if the person is severly injured they cant heal them persay and their partner will come over with a stretcher(those small orange ones)and strap them to it and his partner will treat the person while they go off and heal anyone else and once he is done he will come back and help him load the person on the stretcher in the ambulance and they will drive off. If someone has been mutilated by explosions or severe gunshot wounds maybe they have a small chance of bringing them back and if they do then they do the stretcher thing.
Just a thought.
