Learning curve

So i just got a game with a guy telling us in prelobby he just got lvl 30 and its his first ever ranked game, then in game he feeds a ton, our caitlyn has half the cs of the ennemy mordekaiser and our garen is rushing IE, dying a bunch to riven and then afking. I try to tell the Ryze to stay under tower focus on farming etc etc and i start getting bitched at and it's just a bit frustrating that people don't listen.

Like, our team kept defending him and stuff but if he does crap and nobody tells him he needs to go practice and just cater to his feelings you'll keep getting some shit players thinking their great, like what was some lvl 30 guy who never played ranked before doing in a silver 2 game y'know?

Not to mention i always put music when i play league to calm myself so i'm not toxic but for once i didn't and i got a crap team n shit, no luck :(

But yeah players shouldnt have to be nice and kind and not rude to teach someone or get reported by your team because your being "rude" like bitch what do you think this is? elementary school? It's league nobody cares about your feelings and nobody should really.
