This is the real problem. Launch day patch they removed the effect that made people stop moving while you healed them. Your revives and heals with the beacon do get recorded, it's just... Really weird how it's calculated. It can get you extra exp if you chart high enough.
Hm, guess that is by design, because I can see people trolling with it. I just need some way to be able to tell the other guy "I'm trying to heal you" with some quick chat command.
