Did you come up with these numbers? Because I don't want unfair advantages for Mordor...

However, I do understand their strength in numbers.

They are actually nearly identical in number. They are both around ~20,000 troops. However I added the special units into it as well. (ie ring wraiths, and the fell beast dragon.)

Ah ok. Well, I approve of these numbers. Make sure to update it as they can die of course.
