Ok, my guess at the new factions:
1. Harondor (?);
2. Khand;
3. Elves that live in the trees;
4. Elves that are wiser and snobbier;
3. Dwarves;
4. Dale;
5. The guys of Beorn;
6. Rhovanion?
7. That city-state.
P.S. I agree with Aradan. No more rebels, more proper and decisive action!
P.P.S. I know that most of those are probably way off.°
P.P.P.S. NVM, a single Elven faction and Hobbits. You said 17, but so far I only see 15 with some emergeant faction (Probably RK rebels or something).
