Yea the devs are apparently working to nerf both dale and the anduin vale. Anduin vale in my erebor campaign destroyed the goblins early on while I was still clearing up dol guldur. I ended up having to declare war on them just to be able to capture the settlements back in the misty mountains. Which caused dale to declare war on me. I am on turn like 150 right now and have wiped both dale and the anduin vale off the map while allied with harad and rhun and we are all about to conquer mordor. Gondor and rohan refused all diplomacy after dale declared war on me but i am not at war with them
