So, I finally got my Barbarian to 70, and while I like the Raekor's change, the 6 piece bonus is still rather weak. I've found it's more useful to drop Unity from the cube jewelry slot and use RoRG, then use raekor's 4 piece + IK 6 piece.

The build, though I'm still missing a few items (Hellfire neck, parthan bracers, focus). Very fun build if you like the Raekor's chargebarian
