Just recently, TSM announced its intentions to leave the League of Legends Championship Series, as the regional league has been struggling to remain competitive and draw in viewers when compared to other regional offerings. While TSM is leaving, another LCS organisation has affirmed that it isn't going anywhere, with this being Cloud9.
Speaking in a Reddit thread, C9 CEO Jack Etienne stated: "We're not going anywhere. This is my home and I personally love working directly on the LCS team."
So while the LCS will look a little different next season, you can at least expect to see C9 present and competing in the region as usual.
