If this community didnt act like offended sissies, and actually played-- all would rise a tier.
People play league of legends for one sole reason: to find someone who they can antagonize until that person retaliates, and then try to get the one who retorts banned.
This method of playing is so prevalent, that in any given game you can literally pick and choose people who will never climb out of certain elos based on two reasons. The first reason is because they think they do nothing wrong, are solely carrying the team even though they are 0-5 against a Darius, and are constantly focusing on every mistake a teammate makes in order to make themselves feel better because they can deflect the blame to someone else for costing the entire team a win. The second reason is that the kids who play this game today are more intent on ruining someone's day or protecting their internet-ego that they can't brush off what people say or ignore a couple of mistakes.
Let's be real here, 95% of the player base of LoL would never run their mouth to anyone outside of the game, or if they did run their mouth and it escalated, then they would get stomped into the dirt. There is no reason for all of this community to project a false hard-ass mentality onto League of Legends, no one believes you could hold your own in the cage for 10 seconds. Therefore, just stop it. Play the damn game, stop trying to get people banned, stop worrying about someone calling you a "poopoo head", stop pinging 6 question marks on someone when they know they fucked up, and get your elo.
