Consumer Smarts - Don't Fall For The Trap: Everything is designed to enrage you...
From emotes (which nobody uses correctly - Most are used to insult the enemy team) To being able to speak to the enemy team (Which you cannot do in SMITE, HOTS or Overwatch)
From unfair ranked match placements To smurfs and premades...
Everything in this game has been purposely built around one core concept. To make the game as frustrating for people as possible. Riot are aware that some people are so shamelessly addicted to League and committed to maybe, one day, becoming an LCS player (which is impossible for more then 1% of the total fanbase) that they know they can make the game as awful as possible and people will STILL play it.
Riot is a real big company, they have their own psychologists. They know how to manipulate human behaviour. (I have a psychology degree myself and I've seen this in this game which is why I do not play it anymore or put money into it). Riot deliberately create things that they know will frustrate their playerbase, from playing favourites with champion balance, to releasing overpowered items. They KNOW that this will enrage the playerbase and cause them to die more in the game.
The reason for this is in the automated banning system. Some players are able to control their emotions during a game but Riot are aware that most of their playerbase are of a younger demographic that have not learnt to do that yet, its the reason why so many younger people are so politically active and then tend to lose interest as they get older.
To the people that can control their emotions... Good for you! but to the people that get angry when they die unfairly or because of intentionally poor design choices... you will get angry and go toxic. Then the system will happily ban your high level account and force you to make a new one so that you need to spend more money rebuying the same skins again and because you've already invested, you are pretty much not going to abandon the game.
Having multiple "warnings" do not really affect this either as the game is still built around the core concept of frustrating as many players as possible and provoking them into toxic behaviour.
It is not a conspiracy theory, its just a manipulative business stance and most business models these days are built around manipulating their customer base, rather then making them happy. You only have to look at Hollywood for more examples of this kind of phenomenon.
Once you accept that everything is deliberately designed in this game to enrage and frustrate you. You can play this game with that in mind and not fall into the trap that Riot has set that some people are unwilling to break out of.
I am sure that people will comment saying "I've had this account since... so and so..." but it does not really disprove that some people are indeed stuck in this cycle and therefore sustaining Riot. Its a very manipulative business model which is far too common today due to insufficient business regulation in both the US and Europe as well as Asian markets.
Don't fall for the trap...
I am also NOT saying "Don't play the game". I am just making people aware of this trap which is fairly common in most free 2 play games but Riot seem to have taken frustrating design to another level. Even if you do not believe me, try to keep an open mind and just look for evidence of that pattern in game, look at champion design over the last few years and balance changes. You will find some evidence to support this hypothesis.
