I mainly run my DH now for gearing it and getting the LoN build to push for fun. My sader was farming 80s in 7-11m with the bot and personal play im over 88 cleared with that but I have grown bored of him.. literally use him for getting cube gems over 80.
I personally run 72s on my DH. 1580 Paragon. 89 Trapped, 87 Powerful, 87 Esoteric:
https://gyazo.com/253eeec90a7f00cba46defe5e490c7f5 Avg 10m rift, 112bil exp.
Have 21k Dex, 474% CD, 59% CC, 1.1m HP.
80 gems on every item. Every item Ancient with correct stats.
Biggest thing is to actually have Vit on everything. Don't get Atk speed on wep instead get Vit. Dex/Vit/X on helm(I have crit on mine cuz it didn't have vit). Shoulders Dex/Vit/Resource/CDR. Etc etc. Everything has Dex/Vit/XXX.
So far in those 75 rifts it only died 25 times.

Also, when I first started my DH for GRs I was doing 65s in the same time with 0 ancients other than a wep and no cubed gems on gear. Though I was in the 1400 paragons at the time using all the same shit as above(was physical at the time cuz I had non ancient physical bracers).
