Every one knows certain locations spawn certain loot items. So when you are after that item you search thoughs locations. To make the game a bit more interesting have all the loot be able spawn in all locations with certain areas having more of a bias to one kind of loot type. EG Medical centers have a higher chance of spawning medical items and mill bases a bias to military items ect. So you look in a barn and there is a surprise there an akm or something a bit out of the ordinary not usually found in that location same for other boring spawn locations. So then you might not ignore all locations in your search. I do get a bit board searching one type of location for specific items. It would be nice to get the odd surprise every so often. And the chance of much sought after items should have only a very small chance of spawning outside there usual locations.
