I would like to see FINALLY some of the 1.0 stuff come back. When the development team makes Cutters Cry, Dzemael Darkhold, and Aurum Vale HARD MODE please consider the 1.0 Dungeon style. The mechanics really made a team of players think and work together.
For instance In DD The second boss and the ghost, positioning, and constantly moving around and re-positioning the boss to adjust to the adds.
