You pretty much summed up the spell ideas I have gone through. I thought about having a Summon Huorn (spelling?) spell that summoned some Ent creatures to help Rohan, I base this off the part in the book where the Huorns decimate Isengard's army after they flee Helm's Deep.

I don't think the Hill People would fit at all, they were constantly warring Rohan even before the time period that is the setting for the LOTRs.

As far what I think is necessary. I have found it best to get as many opinions as possible when it comes to modding, then take those opinions and form my final course of action according to what I think after hearing those opinions. When I was working on Haida Gwaii my mod became better to me because people were able to provide different insights that in turn influenced my decisions in the mod to a better end.

On the other hand, I created a mod a long time ago for the original Age of Wonders. I called it the "Heavenly Ruleset" and I changed every version of it according to the opinions of the Heavens Games Community. I ended up hating the mod (I kept this to myself) and even refused to play it in SP or MP once it was finished, a shell of what I envisioned, all because I didn't take their opinions into consideration; Their opinions guided my modding completely.
