Carry yourself out of EloHell
All it takes is ONE bad apple to make sure the game is a loss. I know it doesn't happen a lot, but it does happen pretty frequently.

This Gnar was the one bad apple. The other team was flaming each other in ALL/ and this Gnar still was a bad enough apple to make sure we lost.
He lost his lane, flamed our Shaco for the first 10 minutes. Then fizz helped him out and Gnar still kept trying to fight Yi top. He raged at all of us, we asked him to leave Shaco alone because Shaco actually wasn't doing that bad, it was just a case of a laner blaming a jungler. He told me "go die". He then went AFK around the 20 minute mark although we were actually starting to snowball significantly hard. We actually were on our way to victory when Gnar made his return. More flaming. Got under our Jinx skin enough that she just started backdooring and dying instead of grouping. The last five minutes of the game was Gnar spamming "nope" and "no". He must have typed that over 100 times.
Needless to say the other team actually came to win the game. Fizz and I were Duo. Both First time champs in blind pick so its not the end of the world. Not concerned about the loss. Concerned about the troll. You can see the graph how it suddenly went downhill.
Acting this way is unacceptable and it shows why the ranked system needs an upgrade. If this were ranked, 4 peoples rank would have been affected by this ONE bad apple. This is the type of person who truly does deserve a permaban.
