While overlooked content changes make me unhappy, your screenshot captions were delightful. I hope this gets some attention and you get the fix you're asking for.
Yeah, the whole "let's lower the level of this lesser-used dungeon in order to make it a broken, almost-never-used dungeon, while removing all of the interesting and desirable loot that used to drop there" strategy didn't ever really work right. Sorry to hear that you're having such a problem with this quest, though you are definitely not the only one.
