Step 1: Stock up on base magic find since you won't be getting any neph buffs. Each class will be different but here's my magic find stats/dps/vit when doing these runs: http://i.imgur.com/B8Aqt.jpg
Step 2: Start the prime evil quest and waypoint to the Crystal Colonadde.
Step 3: Just run past every single portal ignoring every mob(they won't hit you) until you get to level 1 of the silver spire. There are 3 possible spawns here : butterfly chick, blood guy, mira.
Step 4: Talk to whoever spawns and kill them, you will probably have to ignore mira and just relog if she spawns.
Step 5: Enjoy the easiest and most broken farm in the game that will definitely get patched very soon, otherwise this game is duuuuuumb.
Note: This can be done even if you haven't unlocked act 4. Simply just choose the quest on hell -> leave game -> join pub -> leave game -> play it on inferno.
What's worse is that as DH there are ways to glitch the blood dude so you take 0 damage, and the butterfly chick only attacks Tyrael. ZERO effort farming."
