So what set am I trying to farm or move onto at this point?
What should I spend my Blood Shards on?
Should I actually be using my Greater Rift keys, or just stockpiling them?
You want to be farming Tals Set initially in order to use the Flash Fire Wand of Woh Spec.
http://www.diablofans.com/builds/70620-s5-torment-x-wohrasha-db-farming It is the best for t10 farming. I would focus the set more around toughness than overall dps because after all... you are running Hardcore. You can craft wand of woh's in the cube with 50 of each mat, 25 death breaths, and a rare lvl 70 wand.
So spend your shards on Tals Pieces.
I would use 40 or so GR keys initially so you can level the 3 gems you need.
In terms of team play and high GR solo play... Delsurs set is what you want. Problem is ancients are much rarer to find that Tals so a good set takes longer to accumulate.
