I hate losing games simply because my teammates like playing metamancer shit.

Like im fine with a normal loss, but when my teammate picks Kassadin Jungle, bitches and moans that he got countered jungled, and did nothing the entire game, that is when I get bothered. It is simply the fact that people are intoxicted in my ranked games and don't pick viable shit. I don't give a flying fuck if it's not meta, don't pick shit like Veigar jungle and Braum mid lane. It's completely fucking selfish and we all know you're just doing it to "have fun" and not even take anyone elses promotional series into consideration.
