Here's the build: https://us.battle.net/d3/en/calculator/barbarian#WTRVYk!bec!cbbcZc
The logic is as follows: You approach an elite pack. Ground-stomp to bring them in a small area around you, then Earthquake for massive damage. Because of Ignore Pain, you can afford to stand in desecrator or fire chains, as the heals you receive from the massive damage of Earthquake + your normal DPS keeps you topped off at all times, and 5 - 6 seconds is usually enough to kill a melee range elite pack.
With Packs that disperse (Ranged), you'll manage to keep at least one on Earthquake (The one I'm focusing on rarely seems to run away) giving you room as now you only have 2 to fight.
Does this sound like a viable build post-A1 Inferno?
