Hey, there's something goofy in your item distribution. My experience is on the map Slipstream, although I doubt it's confined to that map.
On the left side, I found 9 items in 16 level 1 ruins. On the right side, I found zero items in 16 ruins. This is more than a bit peculiar. I doubt anyone would notice under normal circumstances, but there's something very non-random about item assignment. Whether it's geographical, or related to the order in which the ruins are placed, or whatever, it creates a vast discrepancy between the resources available to different players on the same map. Something worth looking into!
