Man-at-Arms Dol Amroth - 5 It can be helpful to have pikes, but I just overall don't really like these guys. I don't know why, not a solid reason, they just don't seem to be that great. It also doesn't help that they are in an army that's mostly metal, and are metal themselves.
Wose Warrior of Druadan 7 - A very good bargain if you are going against orcs, uruk-hai, or goblins. Very cheap for all the special rules, and elven cloaks on all of them
Knight of Minas Tirith - 6 A decent mounted warrior. They lack fight four, but have defence six and lances.
Wood Elf Sentinel 6 - They can make a big difference, or do nothing at all. Eldamir madrigal is the best spell, and can really be helpful to keep a troll out of combat, or move it into a bad combat (for it)
. They are just as fragile as wood elves but come with elven cloaks which helps, they also have two wounds which is really helpful in keeping them alive.
Castellan of Dol Guldur - 4 Terror helps them keep that precious will by letting them get charged less. But these guys still cost 65 points for no might, a hero you will have to take courage tests with once your broken, no stand fast, and he can only fight a max of 12 times.
Easterling Kataphrakt 3 - Heavily armoured horses, but only fight three and don't get lances. They also come from a list with few options, which is why they are so much worse than MT knights.
Black Numenorean 6 - Defence six and they cause terror. Can be good backed up by orcs with spears, but against elves the whole terror thing isn't going to do much.
Orc Tracker 7 - The best orc shooters. They do have defence three though so they get ripped apart by elvish and dwarf bows. Moria goblin prowlers with bow are better. (though the extra movement of the trackers can be helpful)
Mouth of Sauron 6.5 - A captain with a bit of magic. I think this guy is really overlooked a lot. He can give a bit of magic support, and won't shy away from combat and dissolve like wraiths will.
King Theoden 5 - Zero will? He will be bait for wraiths very quickly. Overall not very good, and he's with rohan so......
