I honestly believe that this "Antique Gear" experiment SE is doing with the current dungeons is an overwhelming success and should be implemented for every outdated piece of gear in the game.

In the 2.2 Dungeons:

Replace all Darklight Armor drops with "Blackened Helm", "Blackened Cuirass", "Blackened Gauntlets", "Blackened Greaves", and "Blackened Boots" to be turned in for Darklight Armor. That would be stellar!
