my first evaluation of balance is: evil is way to strong
- no problem to take early rihan and arnor city
- no problem to take early osgiliath.
so the momentum is clearly on evils side. easy to balance tuv early with better momentum and growing income. i guess you should do something for the good side:
a) give some more units around osgiliath to gondor and some more units to rohan
b) make few good units stronger.
a or b or even c. di somethng for the good
