It seriously does, the balance of the entire game is throw off, and if you get those people who won't surrender because of pride you waste 30-60 mins fighting a losing battle.
It's not cool at all.

I think we all are aware of how annoying AFK players are, but that's what the report feature is for. I am sorry you had to deal with this, but I don't think the Feedback forum is the best place to vent without a possible solution in hand. How do you think this can be solved? Were they afk during pick? because if they were I just posted a poll offering a solution. If they left during game, you can just stay at base, jungle, feed the enemy to make the game end faster if you think they aren't coming back. If it's close, you should play it out, the longer the game goes, the more swing an Ace or even a single kill will have.

Adjustments should be made when when someone is afk or even just wandering around without doing anything. I think instead of allowing players to rejoin at anytime, after say like 5-6 mins, they should not be allow to rejoin and stats for the remaining players should be readjusted to compensate.

Or be allowed to surrender at 15, and require only half the team
