Heya!
One reason that no one answers here could be that this topic has been aleady discussed often. A lot of topics on this forum deal with the map question!
I guess it's quite hard, to get everyone's favourite map on the server, while no other player is unsatisfied.
As far as I know, the server has a automatic random map decision system (or whatever that is called
for more info on that ask jay...) and a lot of maps are uploaded.
So after every map this system chooses randomly the next map...
I agree that it is bad to see if people leave, bcs. a map is not a very well known or maybe not so good one.
But in this case, you can always ask a high admin to maybe do !next map.
If most people agree, it will be done anyway.
And some of the higher lvl admins can also choose and load maps, so just write a PM.
Further I want to say, that a lot has been done, to keep the server alive! It exists now for many years... AND I guess it would not if the Leaders wouldn't change the map rotation from time to time.
I guess you will find other map rotations anyway, bcs. it is arranged constantly...
Hope that this answer will help you and others to accept that it is not always that easy to satisfy all players
