After a good year, Parth will no longer coach Team SoloMid
Even thought Team SoloMid, the top North American team of 2017 had done pretty well, they have decided to move on further. With the 2018 league system, there will be many more teams in the NA LCS, making it much more competitive. This has forced TSM to improve further to keep their position as the top team especially due to the fact any of the new teams have extremely deep pocketed investors / parent companies.
That said, Parth will continue to remain in the TSM organisation, opting to move out of a coaching role, into a general manager position. This means while he will be less hands on with the competitive aspect of the team, he will move toward a more business orientated role.
