Now here goes in battle damage to equipment is part and parcel of any war / battle and even some games have added this feature on as part of ongoing costs . Well brining it back into KAW terminology let's say your this lil guy who has no allies , pots or even gold out he can happily attack me and depending on what I have out each successful attack can be expensive . So I pin and scout cause maybe 2-3 mill first steal is hardly worth the effort however what if after a certain amount if successful attacks / steals / assassinations or scouts on him causes a % stats of the equipment to be reduced until the damaged equipment is repaired. Costs would be and damage would vary for each item but to the lil guy having his precious EE equipment damaged would become expensive to repair as he would have to first unbank his gold and run the risk of incoming then have to pay to repair until next time
So you want another negative aspect introduced to the ee/warring side to further deter players from pvp, as if people don't already see enough cons from it, such as not making as much gold from an ee war as in an eb.
How would it possible deter pvp ? keeping them pinned is not enough especially when they have nothing to lose so why not after a certain amount if attacks damage your opponents equipment. Hell it might even encourage them to hit back . I understand if u have a lot allies you can be stripped but then what ? Damaging their equipment to the point where the become infective would indeed change the style of play.
