M3C is doomed. nAts playstyle, which was integral to GMB's success (nAts was like the best player in the world considering his supportive role but yay level of ACS) in the past, is as expected no longer as impactful. People have adapted to it to some extent and others adopted it. Emerging superstars like Marved, MaKo, sScary are arguably on his level if not better imo. The only reason GMB even came close to qualifying last time was because Chronicle popped off like the undisputed best player in the world for several months; he can't maintain that form forever, and that is realistic. Averaging 1.52 rating with mostly support agents was what kept them super competitive.
Now, GMB has lost their Ukrainian analyst (check liquipedia) due to the war, and the war might have also quenched their hunger if past Berlin victory hadn't. They simply can't participate internationally, this has to reduce their hunger. Other teams are eyeing on at least one major, they are going for it.
