Future Characters

I know Kings is still relatively new, but what characters do people want to see in future expansions?

Personally I want to see Cirdan to round out the Elven leaders. Most of the other significant characters are also less directly powerful, such as Eomer and Eowen. Maybe a "heroes of middle earth" or "lieutenants of middle earth" for these folks. The design challenge would be to have them useful enough to be worth fielding but not too game changing since they shouldn't be on the same level as existing characters.

I'm also not sure how much is available for Shadow. Grima Wormtongue would be great. I'm not too familiar with the deep lore so I'm not sure how many named orcs and similar underlings are left. It does seem like they'll hit an upper limit for shadow before the free peoples despite shadow already getting a lot less characters.

What are your thoughts and hopes?
