I usually go on quiet servers and i get a lot of loot skulls if its just me and a friend. I think it's because there is a set amount of loot containers per-server, so it would be something like this. Keep in mind that they do reset the servers more often then you think.
Loot pouch=10,000
Loot Chest=1,000
Loot Skull Chest=100
To prove my theory, I was at Abassa Darkhart for two hours. I only got three skull chests. When I went to a quiet server, I don't remember which one, I had gotten at least for in less then half an hour. So maybe it DOES rely on how many people are on the server. But my theory is kinda of opposite to yours. But someone try it, tell me what happens :P
PS Yea yea, your gonna go with the luck theory again huh? But like I said, at least TRY it
