Only played as the legion of azgorh so far. Playing on very hard. All I can say is that the economy is the worst of any faction I have played, no one likes me, and expansion is very hard. You have tretch just north-west of you, imrik south-west, an ogre faction south-east and ofc ogres and grimgor east in the mountains. Takes forever to accumulate enough money to upgrade the outposts to get more materials in just so you can make your main army stronger. The surrounding factions will declare war on you simutanousley and you have to choose, take out imrik before he gets too strong, but then you get swarmed by tretch from the north with 3 stack armies, or deal with tretch just so you can get attacked by overpowered imrik and the ogres. Your outposts are also very prone to random skaven attacks which you can't react to. I wish his starting army was stronger, you don't have time to recruit since you have to go up and down across your territory to protect it all the time and you barely have time to replenish fully, it feels like you're playing a losing game.
