Ukraine is in CIS (the region) just look on HLTV or a site with common sense.
As for aardis, latvia should really be included in CIS (the region).
Just like saying EU != European Union, CIS != Commonwealth of Independent States but rather refers to the general eastern european and west asian region.
Navi is not an easy team to beat, for six bo3 loses (they're 4-6 for 2 Stages) they lost 0-2 once to M3C only. They're real contenders for Last Chance.
In addition, CIS players are very strong in Valorant, from all 23 Sub-regions in Valorant (23rd is CIS which one is cancelled). CIS players are in 8 of them. Name any other Sub-region who have it more?
