[Agema]

Anyone leaning heavily on mages or bless troops from the capital will be messed up by having the capital nailed. It's not just that though, but a capital can be something like 400+ gold: 40 basic units wiped off your opponent's recruitment, or 2-6 mages lost who could otherwise be researching nasty new spells or chucking Evo at your troops. Not only are you ruining their production, but if they want to sort their rampant unrest out, they're going to have move a load of troops that could be otherwise fighting you to patrol their capital instead.

If you have troops with unrest raising capabilities, it's a whole new ball game. Start the unrest rolling with a couple of remote spells and do the rest with spies.
