I would like to see some sort of NPC similar to blockades that can attempt to steal any one of your planets randomly. It can fail just like any of us and you should be given a chance to get it back as usual. I guess it could be a percentage of your attack is what they can deal so regardless you will eventually lose a planet and be given a chance for a reward. I don't know if this would mess up the balance of the game or what not I just feel like it could mix it up and different rewards could be given for the more difficult npc's that take your planet. And you should be given as much time as needed to get your planet back but if its scanned by someone else they can take your planet and reward. Don't know if something like this has been posted but I like the idea.
