How often can you raid? The nearest Teuton to me raided with twenty club swingers. If it wasn't for being able to raid my cranny, he'd have gotten nothing. As it is, he came away with 14 iron only. When can his troops next raid? I want to keep my resources low to keep blanking him out, rather than trying to kill them off in defense right now, that will come later.

As far as defense, for walls, what do they do? Can they kill off attackers in and of themselves or give your defending troops a bonus? Do they get consumed/destroyed in defense the way defenders would be killed?

Will enough profitless raids get me passed over as not worth attacking?
