Bro globals can't even compete on faceit. Trust me I know from experience on both ends of the equation , being global then and being rank 7 now. tier 3 pros at WORST have less aim than a faceit level 10 . But even then not most of them do.

But even he is far better than any typical faceit level 10 player. And in a different universe than any typical global
