I rather have an AFK than a feeder.
Seriously, if you're tilted beyond the means to calming down for the game, rather quit the game and take a rest than feeding the enemy on purpose to necessarily ruin it for us too.
Being tilted in this particular game is commonly normal and at least SOME of us will understand it if you're so emotionally compromised that you can't play anymore. But for the love of god, people who start feeding out of tilt, you people confuse me.
If you're already going to cripple us at least mitigate some of the damage, a 4v5 can still be won, a 4v6 not at all. At least do ONE good thing in your horribly lost round.
Rant over.
Edit: Not just any casual feeder. I mean an actual, real inter.
