Riot put an option that lets people take over someone who has been disconnected for 3 minutes +
Example.
Player 3 on blue team is playing Cho Gath.
Player 3 disconnects for over 3 minutes.
New section in League page allows you to find insta-ques but in exchange you get placed into that game, you can see both scores of the team and the gold you'll have.
Player 3 decides to accept despite being on the losing team, Player 3 continues as Cho-gath.
Game is over
Blue team lost.
Player 3 loses a bit less LP ( Only 2-4 less ) than a normal ranked game.
Seriously.
