Right, well this is all very confusing as I haven't played Moria or Angmar before. How about I let you know what I have available, and then you try and build something for me around it, pointing out worthwhile purchases? I don't have to use it all, but my only stipulation is that I want to use the Witch King.
I have Witch King on Fell Beast, Ringwraith Ft/Mt, 25 Shield Goblins, 28 Spear Goblins, 21 Goblin Archers, 8 Warg Riders and a Plastic Cave Troll.
As far as the archers go, they're pretty useless, so is there anyway to easily/cheaply convert them into something useful?
And one last aside - am I barking up the wrong tree? As far as available models, I have a decent pool of Mordor I can expand too. Sauron, Witch King on Fell Beast, Ringwraith Ft/Mt, Troll Chieftain, Mordor Troll, 2 Easterling Captains, 2 Easterling Banners, 7 Metal Sword Easterlings, 5 Metal Spear Easterlings, Mordor Siege Bow (Two Crew), Haradrim Captain, Haradrim banner, 18-24 Haradrim Warriors, Mouth of Sauron Ft/Mt, Gothmog Ft/Mt, 8 Warg Riders.
