Can you ever have enough???
But yeah there are actually a crapload of great, user-developed maps that were available before, primarily on unofficial servers as official servers seem to just rotate the single-player maps through a cycle. Dont understand why we dont have 30-40 of these greta maps added in, especially since you can upvote and downvote maps in-game now. Might as well add all the maps and let the players decide by voting in-game.
