So I finally decided to do that class hall quest where you get to kill Il'gynoth and receive a raid cache. Figured the easiest way to do this was to join LFR and deal with it. After almost wiping (really we had like 5 people alive at the end), Titanforged 880 Goblet of Nightmarish Ichor dropped from the boss. Needles to say, this made me giggle a bit. I'm running around with a 880 LFR trinket.
Now I have almost no reason to kill Il'gynoth on mythic
The cache gave me a 865 cloak, a whooping 1% upgrade over my old 860.
