These are some really interesting suggestions. I believe the AOTR team's ultimate plan is for Inn units to be map-specific rather than faction specific (or maybe a combination of the two).

The inn units that seem really work well are the ones that fill a (deliberate) gap in that faction's capabilities, giving them more options. This makes the inn a really important strategic element in the game. So from a gameplay point of view it is easier to figure out the desired inn-unit functions perhaps for factions that are deliberately geared towards a particular style of playing, like Dol Goldur. More flexible, all-round factions like Isengard and Gondor are harder to figure out from this point of view.

Some thoughts on a few of your suggestions:

- Isengard: The Ruffians seem the obvious choice here - the men who fought for Saruman in the Battle of Bywater and who were his henchmen in Bree, the Shire and beyond. There are some good sources in the films - various disreputable, Bill Ferny-like characters seen in scenes in the Prancing Pony. The function is harder to figure out, but perhaps something involved with spying rather than combat.

- Rohan: I love the Woses/Druedain idea, as we've been given tantalising glimpses of them in the 'Skill of the Woses' power. There are many directions this could go in - healing, scouting, poisoning, or teleporting by use of their 'secret paths'.

- Dol Goldur: Easterlings work pretty well considering the Lore. There was an Easterling clan called the Balchoth who were knocking about in Mirkwood long, long before the events of the Lord of the Rings but they could be a source of inspiration for a unique design, perhaps some true believers who have sworn revenge on Eorl's descendants.

Would you consider adding Isengard Orcs as the Isengard Inn Unit instead of Moria Screechers??

I think a better fit for an Isengard Inn Unit might be Ruffians: the men Saruman enlisted when he took over the Shire. The design cue would be the Bill Ferny-like characters creeping around the Prancing Pony in FOTR and DOS. Perhaps they could function as spies of some sort.

On 'Voice of Curunír' vs 'The Ruling Ring': When Ring-Hero Saruman is implemented I think it would be more lore-friendly for him to retain the power to convert permanently rather than temporarily even without the Ring.

Perhaps this could be balanced by making 'Voice of Curunir' affect a much smaller radius, only possible to cast very close to Saruman, and have a long recharge time?

(It always bothered me in the original game that you could have a Create-A-Hero who could permanently convert enemy units whereas Saruman, who is meant to be the best at that sort of thing, could only convert temporarily.)
