Why do NA teams put so much priority on Scrims?
NA players are becoming objectively worse than EU players. Even EU imports become worse players the longer they stay in NA. Solo Q in NA needs to be an environment that can can produce a high concentration of good players because the region simply doesn't have a high enough volume of players.
I see no reason why there are 100-120 players between LCS and Academy who are meant to be 'the best of NA' and there's maybe 50 of them on the Challenger Ladder.
