Matchmaking is perfectly balanced, just play better

Every match is a wonderful opportunity to test yourself against incredible odds. You should be eternally grateful for all these difficulties you face. These harsh lessons make a better player out of you, and you should embrace them. Sure there's some smurfs, but every smurf teaches you something incredibly valuable. Sure there are duo's abusing the system, but you don't need to be mad about that, you can take this opportunity to test your skill. The system is perfect by all measures, and it is you who must improve yourself. Any perceived unfairness or unjust loss of LP will be rectified in later matches. It is a study in long term determination and consistent effort even in the face of hopelessness. You not only gain all this experience by playing through the losses that are placed in your way, but you gain mental toughness and vigor.
