The most recent game I've been playing is Playstation All-Stars Battle Royal, and the online is great, but I seriously can't get through one game because I always "lose connection" with the host, but really just rage quitters and people trying to save their score. That's the problem with have stats and win streaks in some games, especially fighting games, so many can't handle a loss in their precious little score, it really just ruins the online experience, and they do get away with it because there are no penalties for quitting.
I know I'm just ranting, but I think there should be penalties for people rage quitting, such as an automatic loss, or losing a chunk of points. Should there be penalties for future games? Are there any games out right now that have penalties for quitting?
