I've always liked Uul-Netol's Embrace, and I was hoping that with slam skills being reworked the high damage low attack speed would work out. Here's some very rough builds I've come up with so far:

All of these are including 50 Rage, assumed with the new Keystone that makes Mana regen apply to Rage.

Blood Stance Perforate is also an option on all of these builds, but I'm not familiar with it.

EQ Jugg - .5 Attack Time .5 Aftershock .5 Bone Nova - 6 Hits per second after initial hit | Lowest DPS ~450k

Berserker EQ Same attack speed 6 hits per second | Slightly higher dps, easier to hit APS threshold

Berserker Groundslam - .36 Bone Nova cooldown, 4.15 Groundslam APS | Highest DPS, ~ 1M doesn't have to hit any APS thresholds
