Teams that won international LANs :
Sentinels (Masters Reykjavik)
Gambit (Masters Berlin)
Acend (Champions 2021)
Optic (Masters Berlin)
FPX (Masters Copenhagen)
Loud (Champions 2022)
Fnatic (Lock//In)
Fnatic (Masters Tokyo)
EG (Champions 2023)
If we look at the number of CIS players in each of these :
Sen : 0
Gambit : 5 (Entire core)
Acend : 1 (Kiles, part Ukrainian)
Optic : 0
FPX : 3 (except Keith and Zyppan)
Loud : 0
Fnatic : (Chronicle and Derke partly Russian)
EG : 1 (Demon1)
10/40 are CIS based.
I think if we make a detailed Analysis with say points and every pro gets 10 if they're in the finals and lose one for a lower placing, we can get a statistical analysis of every region wrt pros.
Edit : everyone telling demon1 is not a Russian, why do you think he faced visa issued for Tokyo? He migrated when he was 10 y/o. He currently does reside in America but is a Russian. He once said it in his stream as well.
