Didn't Camate say that there will be a point based system for dungeons to obtain a lesser version of Darklight? either way Yoshida said that dungeon runs will be much longer dungeons will be much bigger so i imagine as it is now you find chests throughout the run the same will be there..so you might get a group of pieces at 1 point and the rest at the end...with the run been so long and much more work involved a guaranteed piece isn't so bad
