I think you misunderstood my question.

I wasn't talking about capturing valleys. I was asking what you do when this happens. You scout all the valleys in your area and pick out the ones that you can farm for medals with little to no losses. After hitting them the troops change to something you can no longer hit without a lot of losses like valleys with archers, pikemen, swordsmen, warriors, etc. So what do you do when you're surrounded by valleys you can't hit without losses? Do you wait a day or do you have to hit them anyways so you can farm?
