Mines are dumb. They are static, almost always empty, offer little to no incentive to raid and are never contested beyond sieges. They are wasted content that could be better used for clan based activities. Take a note from Shadowbane's mine system; one of the most fun aspects of that game that created daily Clan V Clan action. Remove rare ores from city mines (perhaps beef up the iron ore or whatever) Add rare ore (and resource) mines throughout the world near player cities and elsewhere. Allow clans to conquer the mines every 48 hours during a window of opportunity (1-2 hours) set by the current owner of the mine. Notes: Anyone can hit the mine at any time but can never empty it beyond 40% max capacity, only the alliance that owns it can fully deplete it. Clans with a conquest tower in the tile can pay gold to automatically mine until at 50% max capacity. However, the rare ore will go into the conquest towers storage and can be raided and looted. If your mine's conquest tower is connected to your player city the resources will automatically be moved to each conquest tower until it reaches your city and deposited in a clan bank or storage. The more towers needed the longer this takes. Mines closer to your city will provide more resources. Conquering a mine requires a clan to first destroy the conquest tower (if applicable) or the mine itself and fight for supremacy by either erecting their own conquest tower or claiming the mine with a clan shard (with a timer). This is just a rough system draft inspired by Shadowbane to demonstrate. It can be tweaked and changed to accommodate Darkfall and the upcoming conquest towers. KhaoZ mentioned Shadowbanes mine system so I made a thread.
