I've seen posts in the past discussing classes infused with the darkness instead of the light. With Rise of Iron, it almost sets up a good opportunity to have Darkness classes. Maybe there will be class specific quests (much like how we had the Sunbreaker, Stormcaller, and Nightstalker quests) in which our guardian investigates SIVA and has been overwhelmed by it. From there we could have dark solar, dark arc, and dark void classes. What do you guys think?
