Reporting/Banning
In my opinion Riot needs to get rid of the reporting system. No other video game before League of Legends had a reporting/banning system. You could say whatever you want and if you were being a dick/annoying/rude people would just mute you. Even on a game like Call of Duty (which is filled with 11 year old kids) you simply just mute them and they're gone from your life. Everyone in League cries about "how terrible the community is" and "the toxic environment". All of that would go away if people stopped caring about it!! You feed the trolls by acknowledging their annoying tendencies. If Riot honestly thinks the perfect system is to have feeders/ragers/trolls/etc. be judged, reported, and banned by other feeders/ragers/trolls/etc. then they are severely misguided.
