Sadly, I was one of them. That screenshot shows my inventory; I had actually just begun a T6 Rift when the buff ended, and you see the first few pick ups were legendary, when suddenly all the Elites and chests weren’t popping legs anymore. Cruel reality!
There is one bonus; it’s possible to obtain blue materials now. (You see my hunger for them in the inventory screen.) One side effect of the +2000% legendary buff was that blue items became almost nonexistent, since goblins hardly drop them, and all the magical items that usually spawn from chests were rolling as legendaries. Since Enchanting armor and weapons carries a high blue material cost, this was handcuffing players in their efforts to experiment with the new sets, or change around their builds.Again, I was a sad victim of this and had actually copied over my Live US account yesterday, since my existing PTR chars had great gear, but no way to enchant anything without any blue materials dropping. And with the +2000% buff, it was actually quicker to refarm all of the legendary items than it was to try to scrounge up blue mats with the buff active, primarily by praying for failed gambles or Infernal Hoarders.
It’s possible that Blizzard might turn the +2000% buff back on again during this PTR, if they make changes to the sets and a new wave of players need a quick way to farm them up, but there’s no official word on that. And this also means that any lingering game creation queues should soon be gone, with fewer players on the PTR (though the game creation delays seemed to have almost entirely vanished yesterday).
