People that Watch League of Legends piss me off.
Its not so much that they shouldn't be able to watch the game. They just watch you play the game while they stand there thinking about how cool it would be to get a penta. Then by time they react because someone is low and they can KS (kill secure) they just die instantly because they forget all semblance of how to play the game while trying to chase that low hp enemy through a wave of assassins.
Just a tip on how to get to a higher MMR for anyone stuck in low MMR. Try doing anything at all that isn't just standing there and watching your teammates play.
