hard truth is that GC is just straight up way less competitive then Tier 3. It's harder for them to qualify for Challengers than to sweep GC not because of the little things adding up like inflated egos or whatnot, it's only because its simply just harder. The team overall is less disciplined for this kinda jump of competition and they've often been getting outclassed in terms of macro plays consistently that's been hard bailed out by flor most of the time.
They make too many mistakes and aren't polished enough to make it whatsoever, but you can't really blame them for not fixing all of that if they've been doing just fine in GC for an entire year. Like they've genuinely been playing the same game they were playing in Brazil, it's just that now they're vsing teams that are capable of punishing them hard.
