Dragon Ball: Sparking Zero is dialing up its anti-rage-quit measures, but players seem pretty unified in wanting an additional penalty: you rage-quit, you lose that match.
Right now, there really isn't any meaningful punishment for rage-quitting aside from increased matchmaking time, but in a tweet, Bandai Namco says it's "strengthening timeout penalties against players with excessive disconnection or quitting rates during online matches." Essentially, it sounds like it'll put rage-quitters in timeout for longer than before but isn't adding any additional penalties for now. And apparently, that simply isn't enough for most players.
