I think it would be fun if treasure map drops were added to the game. Basically when you find a treasure map as a drop you have to complete a series of quests to earn the treasure map's reward. Included in the treasure map rewards would be stuff like pack item drops such as the new spells. The higher level the map and the harder its quests the higher chance of getting something good from it. Friends could then travel together to try and finish each other's maps and the maps would give something to do for those who have already finished all quests as the maps would active the quest arrow for the map quest series. Maps could be dropped from main bosses in towers since players play those most of the time during end game, waiting for new material to come out. Stuff like crown wands would be an excellent reward.
