We’ve got no imminent plans to add them to Adventure mode. We don’t want to rock the boat too much in terms of difficulty there. Some of the combos really need some Chaos Wastes boons to make them not just turn people to paste. It’s not impossible they will always stay solely in the Wastes but for now at least.
@Fatshark_Hedge you’ve probably already seen it, but I would like to point to this thread regarding monsters:
Just as a reminder monsters aren’t necessarily too easy depending on your party comp, and trying to fix this issue purely through changes to monsters themselves is likely to just cause even more problematic disparity between monster kill times.
