Another thing is that EA Van/Hel units should propably cost more resources, at least Helhirdlings. IIRC those units even use magic armor, so it could be even justified (other than them being too easily massable now).
And Ulm, hmmmm, I think the randoms on the smiths should be 25% instead of the 10% we get now. Ulm is not supposed to be a mage power, but even in the rank of mago-phobic empires (LA Man, Marignon etc etc) they are really weak on the mage departament and while the randoms are interesting the 10% chance to get them is a consolation prize. I'd add capital only Grandmaster Smiths who get a 100% random, but that's just me.
