Definitely true there. Anyone who is a medic should be able to heal anyone else. I can heal HPs on myself, heal HPs on gang members, lower hospital times for myself and soon for my fellow gang members. If people are concerned with the healing of others, you can make it so if somebody tries to heal another person in the hospital online they have 15 seconds to decline it (in case they want to stay there). If declined you still have a chance to heal them but now at a penalty to get caught doing it. I would want others to heal me if I was not able too.
If I was to see somebody shot up and wanted to heal them I would not get told I couldn't because they weren't in my squad, division, whatever. Sure, I may have to hide behing a tank, humvee, car, whatever if bullets were flying but I would probably get the chance to help them.
Let us heal please.
