I was thinking there should be a new area on Earth or another planet called the frontier. I would be a place for higher level people( 25 or so) and it would have high level enemies. The enemies wouldn't be the only thing you have to worry about, the factions will be at war with each other. You will have to fight enemy factions for control of 12 strongholds scattered around the map. When you take hold of the strongholds you gain faction reputation unlock faction missions to complete on the frontier. Faction vendors will appear at the conquered strong hold and give exclusive gear you can only get from that strong hold. But along with enemy factions raiding you the Hive and Fallen will constantly be at odds with the factions and each other constantly attacking you and can even take over your strongholds. Level advantages will be on so it will be harder for lower levels. Give you feedback and options on the subject please and tell me if you like the idea or not
