I think you're really just running into a case of supply and demand. Before the new loot was everywhere, it was pretty rare to see a legendary that wasn't so encumbered by negatives as to be largely useless. Now, even without wearing luck (though I am generally in Fel), I pull a few high end arties per hour... without even trying.
Supply shot through the roof, and demand decreases, as even if antique or brittle armor lasts a long time, so every time someone does drop 10 or 100 or whatever millions on a ring, they "never" have to again.
