Power points I did not specify, I shall leave them to people who know balancing. If you could do that; it would be great.
Perhaps a spell named "Supernatural Allies" for the Mewlips and the Lintips; if you feel it is a good idea replace arrow volley with it and add the units to the list; as any new units we have (Even temporary spell ones) have to be added there so we can describe them and show an image. Brilliant idea to have an Ent-Wife hero; that is a stroke of genius, she can be summoned along with the other for a short time.
Into the East would turn the Wizards into their forms after the civil war; so Pallando could become "the blessed" (by the Valar) so he could bring peace and Alatar becomes "the Fallen." My idea is more "saruman of many colours" spell where it is just a passive boost to mirror the other wizards system, not adding any abilities (Not to hate, but I don't think a wizard would wield a bow) and as the spell has a unique effect depending on which sub-fraction you pick it benefits them in different ways. Actually perhaps it could upgrade one thing, a leadership aura; before the upgrade they could have similar auras but afterwards Pallando's becomes more powerful while Alatar's changes to scare enemies.
In terms of heroes I see it this way:
Court (Hero Focused):
Scout (Elven Herald)
2 Paladins
2 Other Heroes (Hoplite? Companion Cavalry? Long-Blade? Vinyard Guard?)
Emperess (I feel no name is needed here; have it symbolise she has give all her being to ruling Dorwinion so she only goes by her title)
Pallando (Mass Slayer to counter cult spam)
Dwarf Lord
Avari Lord
Tauriel
There needs to be a good mix of elven and human; and male and female (Perhaps one paladin is female and one of the 'other' heros)
Cult:
Scout
Warrior
Cult Leader
Bladorthin II
Alatar (Hero Slayer to counter court's fewer but more powerful units)
Miltia leader
Rebel Leader
No elven leaders or female leaders bar one- cult leader is female dark numerorian sorceress from Umbar who is serves Sauron somewhat but true loyalties lie with Umbar and cult of Melkor. Presents herself as an ally to Alatar (Good numerorian) but is secretly shaping the cults to worship Melkor and defy Sauron without him knowing. Invokes parellels to fall of Numeor.
Regarding Ent-Wives; even though they serve the light we must remember the cult side is made up of three groups: peasants who just want to live in peace, nobles who wish to ally with Rhun and Sauron and the Cultists who worship Melkor secretly and in my vision the ones who helped the Ent-Wives especially were the peasants who lived near the forests; as such they would feel a heavy debt to aid the peasants.
Regarding the Mirror Tower, I feel it is very appropriate as the sun in Middle-Earth is the light of the valar and its light is the bane of Sauron's creature; by making use of the sun it alludes to the the relationship between the Valar and creatures of shadow. A possible name for the tower could be "Mirror of the Valar"
Could you please add my link to the first post with a "this is a concept being developed" message. I shall do a document of my concept of the Men of the Shadow as that is the best developed.
Something slightly offtopic but I found this:
http://merp.wikia.com/wiki/Ad%C3%BBnaphelI am really annoyed she was not a hero for mordor as having a female nazgul would have been really unique, especially considering she was a numeorian, ruled Harad and kicked butt. If by any chance a dwarf system was adopted for the evil men I would be in favour of her leading the "Shadow of the East" spell army for Harad.
