This is actually a really good match and hard to decide who wins.
FPX plays in a way where they have flex players that try to anti strat their opponents and build comps around their comps
PRX plays in a way like no one else, with hyper aggressive double duelists comps, forcing the enemy team to give them the space they are fighting for.
It's gonna be interesting to see whether FPX can actually counter PRX or not
