Hello Barocca,
That's a large list there, may I offer a suggestion?
Please don't think I am being critical when I say the unit roster is too long, I am sure it will introduce some fun in SP campaign.

For MP, I think the simplicity of unit choice is what made STW so good and this simplicity should be considered when refining a Mongol roster. The Japanese stats already used in this mod should be carried over to the Mongol era (with or without guns'n'monks) and the Mongol unit stats based on these. I think play balance would be best achieved this way.

Out of interest, have you ever considered a Korean faction? Remember, Japan attempted an invasion of Korea during the Sengoku period (well just after I suppose) There are a number of handy units already mentioned that would fit neatly into their roster, making this another interesting option.

I have looked at the 11b unit stats, I'll offer some starting stats for the Mongol units if you like?
And if Beta8 is going to be tested, I'll install it and come along for the ride

.......Orda
