Heroic is currently on long win streak, with zero games dropped this entire EPL. Gambit just won Katowice and are taking this team to a 5th map in a BO5 grand final. And somehow this isn't "good" enough for you? Even if they lose, they're easily in a position where any change makes absolutely zero sense because they're at least a top 2 team minimum.
"They changed supra for Hobbit not because they werent doing well, but because they saw an opportunity to become much better than they were"
They took a risk because they were stuck in tier 2 CS tournaments and peaked at like rank 25. This is completely different compared to a potential top 1 placement after a streak of wins, including a big win at Katowice. Taking a risk here would be incredibly stupid and your logic makes no sense.
