Dear League of Legends players,
There is no report for playing badly, picking what you want, building what you want, etc. Also, no one in all chat cares about how bad your team is. Stop asking in EVERY SINGLE GAME the others to report someone. "But they are trolling." No, they don't, you simply made that up.
Stop your crying, wipe the snot from your nose, SHUT.YOUR.FREAKING.TRAP of a mouth, or in this case, get your hands off the keyboard, and play the freaking game.
