With all the nightmares in Season of the Haunted, I was hoping that the old nightmare mods could make a comeback. They were only usable in Nightmare Hunts and only on Dreambane armor which was the main focus of the Shadowkeep expansion. I've already tested to see if they work (they don't) and I'm hoping that maybe they could be revamped to have more of a role against the ever-increasing number of locations where nightmares are popping up. Especially since we haven't really gotten any new or interesting mods this expansion for build crafting spare the raid mods.
