"Healing others gets you a LOT of xp (more than you can earn by killing, by a long shot), and healing yourself gets you nothing."
I just know that three friends are going to go medic and friendly fire then heal while the bots have a whole match to themselves. They would probably stand beside a supply case and get infinite needles and ammo. I know that damaging a team mate will get you negative xp, but it seems that what you get as a medic would outweigh that. Do you think this could be a problem or lessen the experience? How would/could you stop it?
