Dust 2 has always been one of those maps that players like to play occasionally and it all depends on the type of player, which varies throughout the day.
After testing and taking polls of players preferences on the servers, some time ago, I found that the morning players and some during the day liked Dust 2, whereas the evening players were more likely to choose any other map, rather than Dust 2, unless they had no other choice of maps they liked. It also goes without saying that familiar map names, like Dust, Office etc, are chosen by the occasional player, because they do not recognise other maps which may be far superior.
Dust 2 is played by the morning players between 8 and 11 AM on #1, because of these findings.
Having Dust #2 on server #2 24/7 is complete nonsense and makes no sense, given the earlier test results and extending the time it is on #1 is going against players wishes as witnessed by the vote count on here.
However I can see your point in posting, which I can see was only meant to be helpful and I thank you for that.
