Leavers

Why do I have to be the victim of leaver in my game, it's so sad and I do not like it. A moment ago I played a game and it was so winnable but 3 minutes in the midlaners leaves, a moment later the ADC. Obviously, we lost because of this and I don't understand why I the one doing nothing wrong have to sit on my ass for 10 extra minutes just to wait for a surrender. This is not the first time tho, no no it happens often and every time I'm, the one doing nothing ronglosses sr. Why does it have to be like this, why can't the game end in the team having leaver not lose sr or something? Fix this problem plzzz Riot!
