(3.7) Dominating Blow/ Kingmaker

Hey guys I'm trying to fine tune my current build mainly gear. Was wondering if you guys have any ideas on a better chest, or what ever to help increase my minion damage output.

kingmaker

I know I can get a Bonehelm which is a huge damage jump.
I also was just trying out If I had a 6 link I would add minion damage.

Seems what I'm lacking is attack speed for my main attack I just got the kingmaker so my gem slots could be rearranged. This would give me maybe rage with leap slam

So if anyone has any suggestions I'm all ears.
