Westernesse mod for Battle for Middle-earth II: Rise of the Witch King

I appreciate all the inputs you've made here, and I'll try to answer them.
ThaneWulfgharn, the idea behind putting both Goblins and Orcs into the first level is to give players a choice between an extremely large swarm of weaker units and a smaller group of stronger, yet not quite elite units. Hence you can during the early phases of battle use Orcs as a main body of your army, and the Goblins as a general blockade or a method of swarming the enemy camps and preventing easy movement.
Then, as you say, you've got the even stronger units, the Uruks, however the Uruks are not solely the creation of Saruman, and in fact the general usage of the term Uruk-Hai refers to larger orcs, not specifically to those assaulting Helm's Deep. Thus there is no need to confine them and say they cannot be equipped with both melee and ranged weapons.
Furthermore, I have said early on in this mod, and continue to hold it as part of the fundamentals of Westernesse, that my main focus is not to be constrained by the lore, but rather create a mod with the primary intent of enjoyment and interest in play. This isn't a decision borne out of lack of knowledge of the lore, but just that there are too many mods out there who find themselves bending over backwards and sacrificing their creativity for the sake of keeping to the lore absolutely. Thus, if you do have any qualms about the fact that Westernesse isn't entirely accurate, then I'm afraid perhaps it isn't the mod for you. Hence the Wretches and Ahyaröa are staying, sorry about that.
On the other hand, the fact that in their early unit classes the Númenórean factions bear strong similarities is deliberate, owing to the fact that, although they are on different sides in the war, in their most basic form they are actually not dissimilar, and that it is more a war of different ideologies rather than different peoples.
The Elven Heroes were chosen based on their involvement in the Siege of Barad-Dur, which is the only point at which they appear in the Westernesse campaign, hence Galadriel and Cirdan are not terribly relevant. Oropher I considered for a long time, but then ended up deciding against it because he died before the actual siege. There would always be a limit of three Heroes per faction, partly because Westernesse deals on rather a smaller scale than the previous BFMEs, with overall smaller horde sizes and such, but also because there is a LOT of work to do in making a mod of this size, and another Hero per faction is another thing to add to the list of things not yet done. Perhaps when the rest is done, however, I will consider adding more heroes.
To answer the guest above, too, I would not consider Sauron as a one-man army, but as a strong component of it, as all heroes are. He is not terribly changed from what we see in the previous games, except for the addition of 'Black Tongue', and is supported by the two chief Nazgul, Khamul and Úlistar, the Witch-king (remind me to change that name, someone made a great suggestion a while ago I just remembered about).
I hope some of this reply answers your queries, but for where you have further questions, feel free to ask :)

Haha, thanks! But don't go around killing yourself, you'll never get to play it otherwise!
