Hmmmm... here's a rough outline of the other faction tech trees.
The NorthA confederation of all of the peoples who fought Sauron, the North is a versatile faction with many options of armies.
Peasant Units:
Shire Farmers- Produce the most resources in a farm, but make the worst troops. Can be trained into either Shirrifs or Bounders.
Dwarvern Miners- Produce no resources whatsoever in a farm, but make the most solid troops. Can be upgraded into Axemen.
Elven Gardeners- Produce medium resources in a farm, and are the best stealth troops. Can be upgraded into Marksmen or Blademasters.
Men of the North- Produce medium resources in farms, and are the solid backbone of the army. Can be upgraded into Warriors, Archers, Riders, or Rangers.
Regular Units:
Shirrifs- A basic unit that can toggle between quarterstaff and thrown rocks.
Bounders- Stealthy hobbits equipped with a bow to fend off the beasts from the wilds to the north of the Shire.
Axemen- A solid Dwarven unit that concentrates on armor over speed.
Warriors- The basic swordsmen for the North, Warriors can be upgraded with Dale Armor.
Archers- The ranged version of their warrior counterpart, they can also be given Dale Armor.
Riders- The sole cavalry unit for the north, these riders use the finest horses in Dale.
Rangers- These mysterious men roam the lands around Bree, protecting villagers from evil.
Marksmen- The finest archers of the North, these elves are almost invisible in woodlands.
Blademasters- The sword-skill of these elves has been honed to the finest.
Buildings:
Farm- Produces resources, but only when a unit is present; builds Farmers, Gardeners, and Men of the North
Mine- Produces greater resources and reduces upgrade costs, but only when Miners are present; builds Miners and Men of the North
Training Ground- Troop upgrades purchased here when peasants are sent in...
Citadel- The center of any self-respecting army base.
Armory- Upgrades purchased here!
Upgrades:
Dale Armor- armor for humans
Dwarven Armor- armor for elves and dwarves; better than Dale's
Fire Arrows- Arrow upgrade for a maximum of six battalions
Barbed Arrows- Arrow upgrade for normal people
Elven Blades- Melee upgrade for everyone
I was thinking that Rohan would have two peasant types: the Peasant, which becomes an unmounted militia battalion, and the Herdsman, which becomes a mounted unit. The Herdsman would manage a flock... a resource producing building that's basically an animal pen. Gondor would most likely only have the civilian, Isengard would have the Orc Worker and the Uruk Worker (adding in super-weak but fast scouts for O.W.) and Mordor would have the thrall (for Easterlings/Haradrim) and the Orc Worker.
More basic tech tree emendations to follow.
