let's not exaggarate. The fact that they made a few foreign transfers don't mean they are one of the best leagues in Europe. For example Da-Yeong Lee won't be able to play any of the top leagues in europe
There aren't that many good leagues though. I don't mean Italy, Turkey, Russia (not that good either) level but the tier after that yes kinda similar now imo.
Lee Da Yeong is a good player, minus her dramas I disagree
