with orcs - bald, without helmets and shields or small clubs, onlt 3 types of weapons... making several random types of orsc will be great IMO. And in book and film they were rather diversified, but armoured.
I'm thinking of doing something with the Ringwraiths... Possibly removing one of the fellbeast riders and adding in two who are onfoot/mounted on a horse...
Nice idea, but I suppose that they should be late-game heroes, giving Mordor a fast harras early-game hero, like in BFME2, would make loads of balance problems.
