Earthshaker - Any builds to this?

Ive seeing other Hammer builds with Backbreaker, Devasting Hammer, but not a Earthshaker. Im looking for a PvE Earthshaker build (Ive been trying Combination Staggering Blow -> Earthshaker -> Aftershock).
With 15 Hammer Mastery Staggering Blow makes 15 second weakness. Max hammer mastery + using Devasting Hammer makes 17 sec weakness but only kd one mob/guy, so why not use Staggering Blow -> Earthshaker -> AS combination to be more effective ?


Guys, i need help for this Earthshaker build.
