The EU LCS will be moving to a league system in a years time, until then, team will continue to get relegated / promoted at the end of the 2018 summer split. As the team had won the promotion tournament into the EU LCS earlier in the year, the team will return to the primary EU LCS.
To prepare for this, FC Schalke had earlier completely revamped the team, signing new talent along with newer coaching staff. While they may not have performed as well as man expected when they entered the EU LCS, they remain a strong team, as shown in the EU CS.
