I agree, but i think we just need a dunedain milita unit and combined with ranger outriders, and normal rangers, they could make a fine military.
1: We won't be seeing mumakil for a while, and 2: All the different Harad factions are actually subfactions (for example, you cannot pledge to the gulf or the nomads, only all of near harad).
Well i guess we'll have to see but looking it up you are probably right which is weird because you would think they wouldn't anounce the setting of later seasons before the first season even comes out.
Well actually all i know is that they posted those maps and said welcome to the second age, and that it is very unlikely that they would have mutiple seasons for different time periods. I know nothing beyond that.
I was thinking just eriador first then i remembered the stybba and i found the other instances outside eriador.
