This is slightly off topic, but still, I feel exactly the same way.
Single server admins can do absolutely nothing about it, believe me I've tried. The problem is there is no universal standard, the introduction of the vote feature practically ended the era of maplists. If I'm not mistaken the vote feature was implemented to end the constant rotation of the same maps and take the pressure off admins to change the maplist. If you were around before the vote feature then you'd understand that this was desirable. However, the feature, coupled with the rapid expansion in public servers, has only perpetuated the problem. Now if you want to play the game (in Euro servers at least) you're forced to either play shazam33, ub_rooftop, grave, temple22, shock or ub_cliffs. As i said, because there are such a wide choice of servers available server admins who run maplists can not retain players on their servers.
I don't think the issue is with 'good' or 'bad' maps, i think the issue is with variety. I don't mind playing shazam33, or any of the other maps, but i want to be able to play a large variety of maps to stop the monotony.
I proposed this idea before (originally Snipens idea), and that is to have restricted voting features. Instead of allowing players to choose anymap they want, the server should select 3 at random and allow players to vote on which one of those 3 they want to play. That way you get a nice healthy flow of new and old maps for everyone to enjoy. You also need some universality; admins must be forced to operate within the same standards otherwise you're only going to widen the disparity between old and new skool.
Ive had many discussions about this and could go on forever, but I'll leave it at that for now.
