I would love to see the bonus chest system return from 1.0. There were certain dungeons that the boss could pop up to five chests. But you had to do a number of things to get the extra chests. 1: Kill specific mobs, 2: Open all chests, 3: Beat the run in a specific time frame, 4: Defeat specific boss(for totorak sense you had a choice of beating one boss where the dungeon could end swiftly, or you could fight the hardest to reach boss and get extra chest) I can't recall if there was another, maybe one for no death but i forget now. This system would make dungeons a little more interesting.
