So we have identified the reasons why everyone is getting little to no resources looted from barbarian villages. In a previous update we removed the resource cost for technologies and made the technologies automatically granted with certain building levels. By doing this, it automatically enabled the hiding space for all barbs. So their resources are now protected in the hiding space and they are using resources to grow buildings. They will eventually grow to a point where they will have the excess resources to plunder but clearly this is an issue for farming, especially in the early game where farming is so important. We are working with game design to address this issue and determine a course of action. That being said, the game is still level due to the fact that this impacts all players equally. Please be patient while we work to address this issue. I hope this answers all of your questions.
