This is a team game guys.
Yesterday I played a game where our jungler, a Rengar, got me 3-4 kills as Veigar off the enemy Malzahar. We however lose ONE drake and then he says "Dang I g2g" and AFK's. After that the split pushing was a bit much and we eventually lost (S3 is just a distant dream).
After some reflection, I decided "Fuck it. I'm just going to play to master my champs and learn more and not focus on win/losses in ranked"
And then I just played a game today where everyone was doing relatively well beginning of the game. Fiddlesticks and I (Malz) stole a drake from the enemy Amumu jungler. After that Fids went up to help Irelia's lane (She was winning in cs). She tells him not to go into her lane, but he does it anyways. He proceeds to get a kill off wu while she is backing, takes one wave and uses the current wave to push at tower before leaving.
Irelia then proceeds to run straight down mid lane and die to Annie. After that she heads to bot lane twice to give Graves more kills. She continues this throughout the game.
Happy to say we managed to almost get one of their inhibs, but meh
tl;dr Why are people so selfish in a team game? (coughBlames Parentscough)
