Is it because it's preseason, and the wins/losses won't have much effect on S7 placement?
But every game I have been in (SoloQ) has been full of flamers, AFKers, and people just pissing about?
"I'll 1v1 you!" , "I have to go now bye", "first time with [champion]" etc
I thought that ranked is supposed to be the place for serious competitive play?
