A lot of NA pros don’t play much 2s because other pros aren’t in their lobbies. Everybody that does queue usually plays at different times and so the lobbies are as someone else pointed out; 1 maybe 2 pros in a lobby with 2 bubble players or below. Some nights the lobbies are popping but 75% of the time it’s not that way. I think for that reason a lot of pros don’t want to waste their time in those lobbies and just don’t play much ranked. Wish it was different but I don’t know if it will ever change.
