Ridiculous loss due to the "LEAVER" system

I was trying to finish my series and that was the second out of 5. Lagging in early game but all good, we were not losing. Then I got disconnected and all I could do was waiting for it comes back. (I tried restarted my routers twice but it didn't work!) Comcast is the only provider in my area and I upgraded it but their service just sucks. I still got disconnected every now and then.

When I returned the game, the scores were almost even but the enemy team was right in front of the base in mid lane. Definitely losing. But later we still won that game cuz their players were trolling and doing bad. So in this case, the system told me I was a leaver so my game result was a loss.

I mean, I wasn't intended to leave the game and I did try to reconnect. And more than this, I helped the team to win it. But I still got a loss??? This system is just ridiculous. What's the point of reconnection and playing 10 more minutes?????

Riot, please take the performance of the players into account, not their internet connection! This way of FORCING a player's game as losing is NOT REASONABLE AT ALL.
