There will always be cheating online in gaming. People are stupid and svck.
Hell, it's the reason all crime happens.
Someone wants to feel good and they want other people to feel bad.
At the very least, in BRINK, you're only rewarded if you act like a good teammate. Hackers, cheaters, and lone wolfers get the short end of the stick, since no stats are tracked to make them feel good, and they only get a tiny fraction of the XP.
