Just a tip, if the other team has a feeder, you should still play seriously and not mess around!

I've seen a few games the other team was messing around because "this will be ggez, we so good you guys suck since I got fed 20-0."

they end up losing, for example my top laner was trolling me personally so I started to fed to 0-8, then I started to cs and actually play and we came back from a 11.5k defecate since they were messing around all game. another one was a guy who raged and went 2-22 and I still have no idea how we won that.
