I called it - ARR dungeons are now dropping individual gear sets with a mix of ARR and later expansion models. Aetherial jewellery is still a thing.

At a quick run through a couple of dungeons:

HALATALI: Doctore's set as before; extra pieces added. Can get weapons from first room detour and the chain winches.

HAUKKE:
Tank: Scale mail
DOW: shoes are Pagos sandals
DOM: Plain halfrobe BUT shoes using the Crimson/Royal shoes from Labyrinth

QARN:
Tank:
DOW: Fistfighter set (though in a boring khaki brown)
DOM: Cowl with mask

CUTTER'S CRY:
Same assorted gear as before; drops new weapons. Got a basic star globe and a BLM staff that looks like Laevatinn.

STONE VIGIL:
Tank/DRG: Haubergeon/sollerets
DOW: Holy Rainbow shirt/sarouel
DOM: Warlock set (basic mage robe)
Weapons drop from first boss as well as final.

AURUM VALE:
DOM: Ruby Cotton chasuble (Lv64 crafted healer) - giving casters access to this and presumably the matching circlet.
