If you run act 3 hell mode and get a 5 stack of NV and play the whole act with the full stack 80% of the time you will get a legendary. I got 3 in 2 today. Had a friend who had never gotten a legendary tr it and he got one.
Now me i had no MF gear on at all just GF, but my friend has 177% MF before the NV buff. He got his a little past the 1/2 mark for the Act
I have other people trying it as well. Today I didn't get on but tomorrow i probably will.
The drops are for level 50 and higher the ring i got sold for 500k very quickly on AH.
So happy farming people! The key is not to loose your 5 stack and you can get that in 20 mins in the first part of the act.
I am giving this farming method away for free because i have friends with more hours in than me and never have gotten a legendary drop.
It's a tried and true method to getting legendary drops.
There is no guarantee you will get one but your chances are 80% better with my method. If you haven't gotten one by cedera you only haev 2 or 3 more elite packsk before Azmo.
If you have MF gear of course you chances go up much better.

I just tried this! Made 3 runs and got 1 legendary ring lvl 55 the first run + 1 legendary pair of pants the last run. I also used only GF gear (about 160)
These were my first legendary items. I know Hell is crap, but I was able to sell the ring for 5 mils in 20 mins.
EDIT: You don't have to play the whole act 3. Just start from the 5. Quest Machines of War and finish killing Azmodan
