@Technature: Check WinLose's comment below. Tl;dr: Guy helped his Dota 2 team win a lot of money, then they booted him for someone else. Ungrateful if you ask me.
@StormyDrake: I don't think so, I rarely heard about such backstabbing and also, if this was often happening, Jo wouldn't have drawn a whole ep on this.
@zitro: Aui2000 is a dota 2 player that helped his team win a 6.7 million prize first place finish at that games biggest tournament. He was kicked from the team just a few weeks after winning in order to get a very skilled old team member back and to switch the roles within the game they play.
