every single team of group A is better than every single team of Group B (FPX assumed with stand ins)
I doubt it. DRX and FPX are both competent teams and XIA is a strong underdog. Group A is definitely better, but it's a stretch to say that they're all better. People were saying the same thing last event.
*Also this match is super sloppy, teams like FPX/DRX take advantage of these kinds of mistakes
