Mythic introduced a small update to the way that expedition resources for the Land of the Dead are calculated.  It appears that these changes are an effort on their part to make the resources from player kills take a larger role in the capture of the Land of the Dead.

The number of Expedition Resources necessary to win control of the Land of the Dead has been reduced to 500, and the number of resources awarded from zone control is now 250. This will make the Expedition Resources earned from defeating enemy players in open RvR have a greater impact on securing the Land of the Dead.The number of Expedition Resources that drop from players and NPCs in Tier 4 RvR lakes and invaded capital cities will remain the same, which greatly increases their relative worth toward gaining control of the Land of the Dead. This change will reset both Realms' current resource pool, but not current LotD control.
