For the love of god, stop forcing people to sit in unwinnable games.
This makes literally everyone unhappy. There are games that are simply UNWINNABLE in ranked and a duo will hold everyone hostage in the game because they can. This is just ridiculous, because sometimes people want to move on to the next game. I am not saying make the vote 3/5 all the time, rather, make it so that you can have a 3/5 vote when the ratio is above a 50:50 ration and the kills are greater than 15 difference and a 3rd tier turret is down.
IE: 4/20 and they have the turret down. thats all clear signs we done with the game. Please stop making us sit in unwinnable.
