I was thinking, seem every time you kill Oro, or lose a PvP etc... you lose an Item, maybe you could have a safe in your cityhouse or even castle maybe, in which you could store items so that they can not be destroyed. It would only be able to hold 4 or 5 items, and you would have to pay to have one. Another idea would to have lockers instead in the Inn or somewhere like that instead, which would function the same, but you would have to pay a rate per game day, if you don't pay, you lose them. I was just throwing this one out there, and it might have been brought up before, but I couldn't find it or it has be locked.
