Loss Prevented

Hi, I've been playing your game for over 2 years now and i spent way too much money on it (back when i was playing more often) i came into an issue with the ranked system and i believe that i am not the only one. As you know we are all trying out best to climb and achieve our goals that we set for ourselves this season unfortunately sometimes its impossible due to individual players that are ruining the game by leaving it causing players to play a 4v5 match which will most likely result in a loss. So far I've had about 5 games where i had a leaver and it ruined my game competently. The only way to fix this would be ban the player for a week for the first time then 2 weeks and perma ban and on top of that the losing team should get a loss prevented, I mean we didnt lose cause we played poorly out score was 29v31 only reason we lost was cause our adc decided to leave at level 10 and not come back causing us being out numbered and lose. Stuff like this make me want to quit the game stop putting money and time into it. If you value any of your player Riot you should implement Loss Prevented in games with AFK
