This is probably the most "Hardcore" Friendly Idea I've had.
One of the biggest thrills I had in XI was exploring a new place before having the map for it. Exploring new areas released in Expansions before anyone had the maps up was thrilling.
Right now though all the areas in XIV come with maps already explored for you. This is kinda boring. So I'd like to propose that any instanced Dungeon has Fog of War on its map the first time you play through. Just for the sake of feeling like "This is the first time this place has been explored.". After that the maps always open to you when you re-visit the instanced dungeon.
Fuller Explaination.
Again people not reading the first post.
I'll try and explain it better and edit the first post to reflect it..
1. The first time you visit a Instanced Dungeon, The normal full screen map turns into a Dungeon Map. But it is completely greyed out. You can't see terrain or monsters on the map itself.
2. As you explore the Dungeon the grey parts of the map become exposed. As long as you are in range of that section of the map you can also see monsters on the map. If you go out of range you can only see terrain.
3. When you defeat the final objective for the Dungeon Map the whole map is filled in, exposing all the hidden rooms or other things you might have missed.
4. The next time you come to the dungeon the whole map is accessable to you for terrain view for all normal areas on the map. Hidden areas are still Fogged but if you know where they are you can find them easily. Monsters can only be seen on the map when in range.
I'm not talking about competely removing the map. I'm talking about making it so you have to explore the map. A mix of the Local Maps from games like Oblivion, and Final Fantasy XI where once you "own the map" which you get from beating the final objective of the dungeon you can see the whole map. But until you unlock the whole map by defeating the final objective you only see what parts you have explored. Anything you've explored stays visible on the map.
