Aye it would definitely fit better in another era. Feel free to change it. I play all my custom nations in EA so I can play them in the same game.
To change the nation to another era, open the rohan.dm file with notepad, look for #era 1, change that to #era 2 (or 3) depending on the era you want to play the nation in.
That reminds me! This nation replaces MA Vanheim. Sorry I had to replace a nation, but I am up to 14 nations now, so I am having to eliminate existing ones

.
Enjoy
