They walked away with the Golden Bow of Quel'Thalas, Shroud of Redeemed Souls, Shoulderpads of Vehemence, Sin'dorei Pendant of Triumph, and some lucky Warrior/Hunter/Shaman walked away with a pair of Tier 6 Bracers. Though Nihilum beat them to the world first, there's no denying they put plenty of work into this kill. Congratulations to Premonition, and good luck on M'uru when Rohendor decides to get out of the way!
I must add, it's neat to see some of the old school sets in many of these first-kill shots. They're still way cool, but you can see Blizzard's trend of making things more and more over the top as WoW evolves. I can't honestly say I have a problem with that. As much as I adore Faith, Absolution blows it away as far as style and the smaller details.
