League of Legends has a much more sophisticated system for dealing with jerks. It has skill-based matchmaking too (does HoN really not have it?), and you can actually be permabanned if you keep being a jerk and don't shape up. League of Legends also tries not to be infuriating as much as it can, so for example while killing somebody does reward the killer, it doesn't take gold from the person who got killed or prevent them from getting XP.
