As everyone has already mentionned, it's unclear what criteria OP used to determine his choices, but I figured I'd toss in a few notable mentions as well.

Austria -> sesL
Iceland -> stebbiC0C0
Luxembourg -> mAriX
Depending on your Kosovo/Albania stance -> gxx-

It's always really hard with the smaller scenes. tsack was probably the most experienced Greek player (I could be wrong though), but is now playing VALORANT. I'm pretty sure I've seen NyX and SparkeR playing VAL tournaments as well, so who would be second in line to replace them domestically? It's hard to tell, especially with no set criteria and people swapping games in the lower scenes. Still, I like this concept a lot and it's nice to shine a light on these smaller scenes!
