Yes I had read Efcluke's thread and now I understand why they are goneHonestly, I did not really enjoy playing on Modern & DNA, there was barely space to pvp on DNA and the islands in modern were way too far from each other.
The maps got deleted by the community itself, though. As I am right did Efcluke make a thread where you were able to give your feedback on the maps, [Favourites/Dislikes], and those two didn't really turn out prefered
However I think that the build team could easily improve the maps and make them quite more enjoyable, so they may re-add them
