For god sake can you stop using yourself as example? it doesn't work when there are 3.5kk users out there.
In over words you again think only about yourself and people like you and say screw those casuals i don't care about them. And telling apart troll and casuals is pretty simple, it is really obvious when someone is feeding on purpose and is trolling his team and another isn't just that good at the game. The only reason why you someone wouldn't be able to tell these apart is when he comes into a game with attitude: "If someone is doing poorly he must be trolling"
