League of Legends
I played this game for 8 years and all I got out of it, similar to Discord, was resentment. I like to think of this cutscene from far cry 3 whenever I hear someone at my job or a friend or whoever talking about their frustrations playing ranked day in, day out, decade in, decade out, all on the same map thats only major change has been a graphical update since 2009. There is absolutely nothing good this game can do for you or anyone else. Unless your career depends on it I would uninstall it and never look back, regardless of how much time or money you spent.
The one thing I like about League of Legends is the worldbuilding and characters, and thankfully they made a really fun card game about that! Until they announced they were putting the game on "maintenence mode" for its core audience who supported it for years. Oh well.
