League of Legends is a MOBA (Multiplayer online battle arena). This means there are many people that play everyday, from all over the world. Since there are that many people, there is no guarantee that everyone is going to be pleasant to talk to. Sometimes you would get a team that would just batter you with insults, even if you're doing pretty well. It's very annoying, that's why I usually play with my friends. When most of my friends are offline, I play with two of my good friends. There is this one mechanic in the game called auto-banning. When three or more people report a person for the same thing, they get banned for a day or so. When the other two people start getting annoying and start cussing us out, we all agree on auto-banning them just so they can (hopefully) learn their lesson, even though it is not very likely. When you get teammates like this, you usually lose because they start flipping out and start feeding the other team, which is when they run into the other team and repeatedly die and give them experience and gold.
In some cases, like the one I had not too long ago, they try to give advice to the other team, although it doesn't work about 99% of the time. It's pretty funny when you play against a team like this, because you're just casually playing the game when all of a sudden you get a message from the other team saying, "Please report ***, he's being an asshole," and you get a good chuckle from that. Even though people get so angry over a video game, the conversations can be pretty damn
funny. It gets very vulgar but the funny part is when the players get angry or take the game too seriously.
Different game modes harbor different people and personalities. Summoner's Rift, the most common game mode and the one that I play the most, has the most unpleasant people to play with. In ARAM, which you play with a random champion, your teammates rarely speak. They usually don't say a word. Dominion has a mix of people that don't speak and scream at you, so it's pretty "diverse".
It is said that League of Legends has the most toxic community in gaming, and I agree with that statement. It's true because each individual has a unique role to the success of the whole team. If one lane keeps dying over and over, that lane becomes known as "fed". If one lane is "fed" the whole team has less of a chance to win the game because that lane will be the strongest person in the game, no matter the size. Nasus, the literal god of death, can get killed over and over by a nine-year-old girl that has a teddybear. You don't want to "feed" a little girl with a teddybear. Oh, I forgot to mention, the little girl can make the teddybear come to life in a ball of flame. She can also shoot fire from her hands. Fire hurts. When the god of death starts dying, you have a problem, so does every on his team. They start yelling, a lot.
