Human Nature and Toxicity
Riot seeks to strong arm players into behaving properly, with their chat restrictions and bans.
The problem is, is it rooted in two things. One that can not be changed, which is human nature. The second, is the game itself.
Now matter how well you play in a match, if the rest of the team is really bad and you lose, your efforts were completely wasted. This leads to feeling powerless. Feeling powerless causes either sadness or anger in people. If you are some zen jedi master, I apologize, but we are not all like you. But coming back to reality, that is just how people usually work. The game produces toxicity because players feel powerless.
Furthermore, people play games or sports for a release of some kind--in sports, you can release aggression, physically. There is an outlet for that through you actions and efforts. In League, you don't have that outlet, so shit talking, or talking trash becomes that outlet.
You are never going to change the fact that League of Legends has one of the most toxic player bases out of any game, UNLESS you do something to help players feel like they aren't completely powerless in the worst of situations.
For example, if in a match you lose 20 LP, but played very well--high KDA, high CS, huge percentage of damage done out of total team damage...these things should factor in and reduce how much you lose, so that in the best case scenarios, while you lost the match, you might only lose 5 or 7 or 10 LP instead.
I can see no reason why this cant be implemented. Players should be rewarded (in this case the reward is less loss of LP) for their INDIVIDUAL efforts, so that they don't feel completely powerless in the worst scenarios.
Riot, you will never change human nature. All of your tribunals and kool-aid talk about toxic players etc is just silly. Its become such a label that is thrown around---"you are TOXIC player"...almost like, you are less than others, you are a sub-human or a monster. You are toxic.
If anything is toxic around here, it's Riot's understanding of people and players. Sad actually, that such a huge game company can be so out of touch with reality.
