I would like to see some content oriented around company Estates. This would involve the Company Leader buying a plot of land for a "X" amount of Gil. This land would be instanced. Once the land is purchased anybody from the company could stroll into it by some designated place on the map.

Once inside the instanced property members would be able to contribute materials in order to create buildings that will be able to be placed on the map where the user chooses.

Buildings:
Wall (Stone,Wood)
House
Crafter's Hall
Guild Hall
Castle
Archers Tower
etc... just some random ideas.

Eventually you could expand it to contain a dock where a LS crafted boat could be placed and a location to contain an airship in a hanger or somewhere on the land.

One possible way to gather materials to craft the buildings would be to have individuals mining for rocks and lumbers cutting down trees and other resources. Or just hand in different variants of materials that would be necessary in order to create that specific item.

This would be used to have company members gather and get ready for raids or eventually have company vs. company raiding on their instances. Even defend against waves of monsters or HNM's such as Behemoth or hydra.

Just some random ideas typed out real quick before I forgot them I apologize for the spelling mistakes ahead of time.
