all the dungeons listed under normal for upgrade finder are not listed under heroic and mythic
We’ll fix that in the next update – looks like something got messed up due to the fact that the non-season dungeons will drop loot at a lower item level than the season dungeons (or at least that’s how it was on beta: heroic/mythic 0 drop at the item levels showing in the journal right now, but when season 1 starts the 4 Midnight dungeons in the season rotation will drop loot 6 ilvls higher on heroic/mythic 0).
