Firstly I would like to prelude my post by saying I think War of the Ring is very well implemented in Edain bar one exception, Mordor. The problem with the fraction is that their unique system does not work well with the mode (Due to the need to level up Sauron every... single... battle), hence I am suggesting that clones of their heroes are made just for the mode, and only for the mode, that level up normally, including Sauron who could be reinstated as a commander. Hence the fraction could be playable in the mode.
