I do feel like it's a problem in the older dungeons as well. When they took away belts they didn't add more chance of getting anything else; the first boss just became shoes or nothing instead of shoes or belt.

On the upside they seem to have added gear to some mid-dungeon chests in the level 60 dungeons but it's still only a chance of getting them. After several runs of the Arborteum I saw a few extra gloves and hats but no shirts anywhere except the final boss.

They're just so frustratingly stingy with this loot when it has even less gameplay value than the levelling gear.
