You do realise that the legendary lvl 70 drops get better as you run the higher torment levels?
It's about being able to survive those levels long enough to find gear that will sustain you at that level.
Also, MF%! I was running in a party with a guy who had 110% MF, I have zero. In one run I found two legs, two greens and a rare ring that was a big upgrade.
I guess it's all about the grind, if it's slow, there is not much that can be done. At least your paragon is rising which in turn is providing a sustainability through points, even if it is a very slow grind.
I'll also add it was about two weeks before I had any change at all. Last night was lucky, I guess.
Where's gumdrops? That guy is a leveling machine!
