But for the price of 1 corpse unit, I can get several times the skeleton units, and when you add the stats of all the skeleton units, they equal more then the 1 corpse unit. The only advantage I see of having better more expensive units, is using less space in your living area.
Something I have noticed about this game is, Quantity over Quality. When I had about 7 skeleton units, I would alway capture archers/warriors, but I just failed to capture a team 3 archer with 4 skeleton units, and a mistress. Quantity over Quality. Does anyone else agree with me?
As you said, the living area is limited.
