even after being out for over a year, there is still no help for anyone who has a leaver on their team. you can win, even if you have a leaver, but the other team has to be significantly worse than yours. especially in 3v3 matches, one champion makes a huge difference. I know that people have ideas to help teams that have leavers, and i think people should post their ideas here. (i know this isn't the first post about this ever, no need to remind me). i just got off a streak of 5 games in a row with people leaving, and it sucks. i dont even want to play lol after it because its so irritating.
my best idea is that if someone leaves a game so it is 2v3 or 4v5, and doesn't come back within the next minute or two, the team with less champs should have the option to surrender early.
also, i think that if you win with a team that has less champs than the other team, there should be a significant bonus (leaver must have been gone for a major portion of the game)
