Korea, Romania, Poland, Japan, Ukraine, Lithuania and Estonia seems to be this big blob of countries where everyone is at roughly the same level, anyone can beat anyone on a good day, with big gaps above and beneath them (although China is a wild card of course). Considering those countries are split between two divisions currently there is going to be A LOT of movement the next 2-3 years.
From Lithuania's perspective, we absolutely could finish 3rd in 1A, and we absolutely could have finished 3rd in 1B had we played there.
And in before Eye of Ra comes here telling how good the Polish league is and whatnot, it has 7 actual Poles in top-38 of players ranked by PPG. 3 of them play on the same line (Wronka-Pasiut-Fraszko). So unless Poland starts playing their imports in WCs, they are stuck at this level with us no matter how much better their league is getting. Even more so considering they didn't have a good U20 generation since 17/18. They are still the best of the pack but far behind teams like Hungary with actual good players playing for good teams in good leagues.
