I Truly think Player Mentality is dropping.
I have just played a game as a Eve JG against a Trynd JG. Trynd Rage quits at around 8 minutes for dying twice. Everything is going well. Then our Top Gragas gets ganked twice by a Fizz and decided that our team was trash and we will loose the game, because he was ganked twice and spent the next 30 minutes complaining how at 15 minutes he was ganked twice saying how those 2 kills Fed the teemo to the point he could no longer fight him at all. AFK for about 5 minutes in base while bitching. We lost that game, because he was just feeding the Teemo and anyone near him kills. While bragging since it will be his first offence he can handle 15 games Mute ban. Then just starts going off on everyone, not racists but just trying to tilt our team even more then he is doing.
How can people like this make it to lvl 30 without quitting the game if 2 ganks is enough for them to throw the game? He was a Gragas by the way.
