2 players from participating LCS team banned before qualifiers
Riot smashes down the ban hammer again on toxic players and leaves Team Solo Mebdi in a bit of a rut. A third player by the name of Rayt3ch has also been abolished from playing League professionally for a year.
Riot goes into explicit detail on why each player was banned, but some stories stick out more than others. 'The Darkwin Jax' for example, is infamously bad mannered and 'toxic' as Riot would put it. His offenses include being reported more than 1,000 times during a 375 game period and threatening to physically injure players, including a Riot employee.
Though no one wants to take action so close to a potentially life-changing event, Riot had to take action and punish the players, meaning no chance for these players to make it big. After several warnings, these players still continued their actions which left Riot no choice.
