Loot A = main loot is being drawn to 1-5 damage dealers, last hit doesn't matter at all. We kept it for achievement purposes.
Let's say Marshall, Arcanist Karl, Nymeria, Lany and Sucri are top 1-5 damagers. Loot from this group has been drawn to Arcanist Karl and Nymeria.
then
Marshall, Lany and Sucri are moved to get loot from Loot B with the same chances, as other its participants
Loot B = Medium Loot, it's for top 6-10 damage dealers + x others from Loot A, who didn't get loot.
Loot C = Noob loot, anyone who wasn't considered in group A and B + those from A and B who didn't get loot
