Sadly not the best idea as the way you make maps in the game now is not the way one makes maps for the actual game.
This is to prevent abuse of the maps and changing it around to the game breaks down completely. As it's also done for safety sake we cannot really tinker around and let anyone make maps for the patch, as then everyone would be able to make it so, and if they had bad intentions many less good things would come from it.
Now it's not a complete bone breaker as there's probably some ways to make maps that users create compatible with the regular FH maps after it's actually done so it's not impossible.
But then there's whole question that most users seem to forget or not grasp, as most of the current maps and future maps has not been made for the main purpose of being cool as a "map" but to fit in and be a part of the world we're trying to create. In the old game it was just random maps spread out everywhere, in different directions, with different environments and broken bearings, nothing really made sense. If you've kept a close eye you can see how all maps are properly connected and environments slowly change to create this world and we hope that it will continue to expand in the future.
Making a map is not quite the "I'm going to sit down and make this one amazing map" as it's more, how am I going to sit down and make this amazing map to complement the rest of the FeralHeart world. There's limitations in some cases on what can be done or should be done, how the world around the map should look not only in it, how it got there, things like borders and walls around the maps, types of objects and textures chosen.
It would need some understanding and would need to be placed in a rather specific place in the game world now. And giving information and instructions and then have people make work just to deny it or ask them to scrap it all together is not really a good way to go, as it needs closer talking and communication which has even so been tricky on a staff level sometimes.
I get that many users wants "in" on the action, and see a good chance now as we're expanding, some users out there are most likely better than us on the staff to make maps too if it was about making a pretty map, but as it stands now I don't see any good way to let users make random maps that makes it into the game, and even if we tried I could see quite some things go wrong.
I think that it's rather safe to say that this is probably not something that will take place in a near future as this new world is still in it's infancy. Hope that explains it.
