Most servers I see nowadays use the same-old boring maps, when there are a lot of them out there, that they just don't try, for example look at this video (No advertising his trailer, but there are some damn good maps in there):

I don't know if I am blind or servers with such exotic maps are hiding, to be honest big servers like Minit, Goonhaven or Shams should use them. Yes the Bridgewars and Normandie are good, but I think more imagination is needed.
Just an idea to try look for better maps every month or so, to see what you can get.
