To be honest, I was playing with 1st Brigade guys many times, and they literally have only few slovaks in their community, which are probably casual players tho. Almost same situation with Team Ukraine, but we have only few good players and a lot of useless wanks like Bodya #nohate. But at least we barely got 7 players (with Shogun, he is latvian), so Slovakia really cant do for now.
For sure they can try to get native players as Zappy did, but those native players can just say that they are not interested or something, you can't be sure for 100% about this, just giving an example how it is in CIS community for now (apart from Rey).
You just need to accept this lads, one coalition should be there for sure.
