Honestly just as easy as the headline says. Players that somehow manage to serverhopp or have a McDonald's Free WiFi Connection and are constant "connected" with an above 120 Ping should be kicked out of the gamesession (especially Ranked games) and get the same temporary ban as you get for quitting. It's a FAST action game and players that have such an anfair timing-advantage over you should not be allowed to further play the game this way. I suggest to even perma-ban players if their ping connection keeps jumping over 100 or 120.
Sorry but if your pc can't handle the specs or your internet connection is beyond awful, stop playing instead of ruining the game for everybody else.
