Minetown

I believe this viewpoint to be flawed as the replacement of dungeons would be a 1 for 1, not just adding them all over the map. This does bring into an issue with some people using the knowledge of all the good locations they want resources from (like sea monuments) and setting up a system where they /warp or /home all around the map after the reset and try to get ALL of the reset stuff for themselves. This is the same issue as when the map was first released, where people could just go out trying to get all the adventure areas completed and take the resources before anyone got to those areas but then compounded with the knowledge of where the locations are. A solution to that would be to have a master map of where you put the dungeons each month so you can remove them and place new ones at new locations and that would a good deal of work... but it would really make the map feel like it always had something new to offer.

The other way would be to make a map of the dungeons and reset them at those locations while providing those locations on Minetown.net and make it into an event. Everyone then gets to run around to these publicly known locations and explore the new dungeon for that month.
