Tizian "tiziaN" Feldbusch's chapter with the German combination comes to an end with BIG's announcement of his retirement from the company, more than five years after his entrance. In March, the group gave tiziaN permission to look into his possibilities outside of BIG, but the 27-year-old was unable to do so.
In February 2018, tiziaN transferred to BIG from ALTERNATE aTTaX, shattering the previous record for the highest transfer price paid for a German player. Before assisting the German team in reaching the ESL One Cologne 2018 grand finals, he was a member of the team that won the ESEA MDL Season 27 Europe Finals and the Global Challenge during that same season. Over the following two years, BIG struggled to continue performing at that level, and tiziaN was forced to wait until January 2020 to win another championship at DreamHack Open Leipzig.
