Really? Wowhead lists it as Nefarian... Can anyone else confirm this?

AtlasLoot says Maloriak but wowhead has confirmed drops from Nefarian.

I can confirm that is from Nefarian, according to the World of Warcraft website:

armory says it's from Nefarian too as does tthotbot

Atlasloot's BWD loot table is out of order if you access it from Atlas. Chimaeron shows Atramedes' loot list, etc.

On PTR the DMC:Hurricane has been changed to use physical hit% for the proc, and it also crits at 200%. The proc rates still seems to be around 5% based on a few 2,000 shot tests.

Tanis, thanks for the info. I was feeling a bit sheepish about laying down the gold for DMC:Hurricane (although, to be fair, i got it at less than half /2 price), after seeing how little damage the proc does for me - around 1-1.5% of my total damage on average in raids. With the chance that I may be speccing out of SV after the patch it would have been a particularly bad proposition.

now, i'm torn. I have DMC:H, Tia's Grace, Essence of Cyclone, but had totally missed the Valor Point purchase trinket... although not sure i want to purchase it if it's not going to be a significant upgrade.. time to hit the test dummies i feel. :)
