Whats do you think about the koreans after you scrimmed them?

They are always on time, they join the lobby after a game instantly (win or lose) The effectiveness of scrimming hours are really insane compared to europe, in 1 scrimming section we can play twice as much as we can with the same time in europe. The teams themselves always try to comeback and they have a good idea of what to do, all the teams have good vision control and buy a lot of pink wards, the difference between europe and korea is pretty big judging at the scrims.
