Really love this idea, I was actually going to make a post about the possibility of a new map being introduced. Most definitely will need tweaking, but thats where the community comes in. This game needs something new to spice it up, and along with other small tweaks and improvements coming in the near future I feel like this is a step in the right direction for rebuilding interest in Battle Dawn.
A contest could be held for possible new map designs with rewards for the best ones, maybe an event could even be held on a map designed by the community? The designs don't need to be extremely detailed as i'm sure not everyone is a top notch graphic designer, however im sure sparks of ideas could lead to something interesting. I'm sure if there are any limitations when it comes to map designs when it comes to the development side.
EDIT: The current maps are also due for an update. Maybe some tweaks can be made to these to make them more visually pleasing and fun to play. This game hasn't seen a visual/map update in a very long time, however I get that there are limitations with using the flash engine.
