Surrender
Please riot, why has there not been like a stop loss of 3-5 points or something when a team surrenders. Instead we get dragged out to 50 minute losses instead of a 20 minute loss. This is a huge reason the toxicity exists in league. Its a huge time investment and players choose to not surrender because that one game they played last year the other team had 3 dc's and we won 60 minutes later.
Please make the point loss less if a team chooses to surrender. Majority of the time the surrender is due to having an AFK, or a troll, or the teams are just so piss poorly matched its ridiculous.
And while we are on that topic, its not that hard to recognize when a game is 4v5, and 90% of my games are 4v5 me being on the 4 side, always. Implement a lesser point loss or a stop loss or something. This has become a huge time sink and its getting even worse.
Wanna reduce the toxicity, then stop the game from going so long to inevitable losses. Put these repeat offender that go afk on each others teams, not my team.
