Well, I'm a table top gamer of Warhammer 40k and I had the current 08 catalouge and I was looking and I noticed that there is units in the LoTR section that should be included or atlest should be Mercs or have certain AoR in the game.
Now I'm no expert on LoTr Lore or timeline so please correct me if I state something wrong, I'm going off the movies and the slight of what I know.
Granted the units that are currently released aren't set in stone but I wanted to throw ideas out there for both good and evil.
Good -
Warriors of Numenor - Could be an AoR around Mordor. Granted there a lil bit old but it'd be a nice shock troop.
Clansmen of Lamedon - We have the Axemen of Lossarnach why not these crazy scot looking lads?
Osgiliath Veterans - An elite troop that was made of remnants of the Osgiliath protectors. AoR around Osgiliath.
Warriors of Arnor - AoR around Anor, could be remnants of Arnor the begging.
Evil -
Dead Marsh Spectres - Evil undead units that are an AoR around the Dead Marshes, could be a counter to the Army of the Dead
Castellans of Dol Guldur - I don't know much but they could maybe a semi-unique unit.
Ringwraiths - I'm sure they'll make there way into the game but it'd be nice to see them as a group of 9 or 10..
Feral Uruk-hai - Merc unit available around Isenguard and Mordor..
Fighting Uruk-hai and Uruk-hai Scounts - I mean two essential units of Isenguard
Mordor Orcs and Morannon Orcs - Basic units for Mordor...
this is all suggestions that I got from the book...thanks for reading..
