Hmm... The way I was originally planning things, that wouldn't work. The free area missions would each have a particular clan for each area. That means that once you have freed every area, you will have helped every clan equally, and have acquired all of their rewards. While your idea sounds nice, I don't think it would execute well (at least for the free area missions), because I would have to offer multiple versions of each free area mission (one per clan), and that would just get too complicated. However, the idea is somewhat appealing, so if you can think of an easier way to implement it, I'll do it.
