Most people don't understand the network aspect of online gaming. The reason it SEEMS like Asians are cheating is because they are far away from the servers (connections have more latency) and the lag compensation is putting them in god mode. It's been that way for as long as I've played these games. That's why custom servers in games like BF4 will specify all players must be from the same region or they will get kicked by the mods. Balanced match making generally means you need all players to be within the same range of latency.
