I am not a fan of the current deep dungeon formula. I would like to see radical changes to it that would transform the DD system into a roguelike setup with randomized abilities, lost actions, passive buffs and so on for solo and group play alike. Ideally existing job and lost actions would be integrated in a way that would have people figuring out rotations as they go and acquire more of them. The aetherpool system I would like to cut entirely. Instead of regular mobs I would like to see a more boss rush focused approach.
