I've been thinking a bit about the structure of box six. I don't think it'd be too farfetched to imagine having two Fellowship heroes: Sam for the first scenario, escaping from Cirith Ungol, with Frodo as an ally objective, then Frodo for the second two. I'd guess that the second and third scenarios would probably be the journey across Mordor (Frodo and Sam, maybe some sort of quest that encouraged Secrecy), and then Mount Doom and the Black Gate, with two separate staging areas. While it'd be nice to have the Scouring of the Shire as the last scenario, I just don't know that it's likely to follow Mount Doom/the Black Gate.
Surely Tactics Éowyn HAS to appear in box five. I'd expect a Leadership Éomer more than a Spirit Éomer, though.
Really? I was thinking a Return to the Shire as the final Quest, with a final show down with Saruman and Grima.
