This post will be slightly different. This is the story of a League of Legends player that abused an easy to play character to propel two accounts into high rank and show Riot the error of their ways.
In Riot’s game League of legends there is a character that was added called Yuumi. This characters abilities are rather simple… maybe a little to simple. One ability allows the character to merge onto another friendly player and become intangible, another heals the player you are currently attached and the last is a missile that you control. Since this character is a support character they are placed in the bottom lane with the ADC player. All of these mechanics combined allowed a player to launch League on two accounts. one account controlled Yuumi and another controlled the ADC. The player then went on to play Yuumi by using foot pedals while simultaneously playing the ADC as usual. You would think that this would make the team lose a player in a way and be at a disadvantage. Well… this player managed to get the accounts to DIAMOND rank before stopping the experiment. It was posted on reddit and quickly reached the top of the subreddit. Since then Yuumi has received several nerfs to the overall healing output along with other thing. This is a good story of bad balance and its results. It is interesting to see the communities outrage when characters are added to a game that take away from the competitive edge by being almost autopilot. This was also seen in the release version of Torbjorn from Overwatch which would often get Play of the Game by dying and re spawning while the turret would kill everyone.
