Makes you really sad. I personally wanna go afk, but I don't want leaverbuster or losing potential LP. When you have a troll in top lane, and a bot lane who feeds off the planet, nomatter how much you help it.
If I had the ability to fine people for trolling in ranked, I would, but that is something out of the grasp of us serious player :C
Personally, the ability to fine people for playing bad, like preventing them playing ranked for the next 3 games, would make me so happy.
But this is not that kind of world.
