As I understand it from my current reading, all the good stuff comes from fighting Cora herself. All the Void Pool can get you are points with which to buy A) crafter items so limited in lifespan that you can't even sell them and B) the worthless "ephemeral" versions of the new artifacts. So like... what's the point? They could have just made the crafting stuff BOD rewards and saved themselves the trouble. They added this whole "new form of PVM" and really it's only for the combat alts of hardcore crafters? What?
