I have also experienced that and think it is sometimes very unfair: You build a castle to be able to defend the area, it gets occupied with rookies and then your enemy attacks with his heroes waiting for such an opportunity, conquering the castle and occupying it with 12 trained soldiers, making it nearly impossible to conquer it.
Sometimes, I also notice the contrary: A building far away from war that wants rookies by default (e.g. an Atlantean tower) requests strong soldiers. This is of course not as bad as the other way round because you can reduce the number to 1 immediately and this one will be replaced sooner or later, but nevertheless annoying.
