Playing my first campaign as Dale and fighting inside Mordor. After taking the Black Gate and destroying two full stack armies my infantry was sorely depleted. I get a mission to take the nearby Orc Encampment. I wouldn't have bothered except the Witch King fled there after I got him down to 3 men. He is there with one other unit so I auto resolve and lose 52 men.
Then I got 3 units of BARDING HIRD!!!!!! At the fortress that starts with a U. I was so happy!
How much better can rewards get than that?
