Before you jump to conclusions, Shadowflame hood used to be Crit/Mastery, it is now Haste/Mastery. Haste and Mastery are both a better stat weight then Crit at the moment for warlocks, so I'm wondering if anyone has any valid input on the ilvl between the two (int/master etc,.).
I actually just rolled off spec on the nefarian helm tonight for fashion craft and I go to buy it and I realize it's now haste/mastery which was surprising to me, I ended up gemming/enchanting it and using it with Cho'Gall's Hands of the Twilight Council in my sites for the off piece.
