I love how everyone thinks they "deserve" to get +1/+1 on every boss, and even +2/+2 on Edda. Amazing. Look, it's NOT that bad, it's one of the fastest weapon grinds, and even better because, if you have them you can level your lower level jobs with almost no effort. You can get the basics down of most jobs while leveling them too. It is not a difficult dungeon, tho it can suck sometimes. RNG in this particular case is not the devil. If they guaranteed upgrades on every floor and increased the silver chest rate, then people would be done with POTD in a week or so. THAT is poor design, and goes against all the complaints of "Quit making content that gets ignored in a week." a la Diadem.
