Kinetic Fusillade Ballista Hierophant

This build has been a blast. This is the furthest I've made it in end game maps ever. But I am a bit stuck now. I have about 35 div to spend which is also the most I've ever had. I know its sad when some player start talking about mirrors worth of gear. Is there something realistic that I can do that would greatly improve my build? It feels like everything I change does not really make a difference. Any suggestions would be greatly appreciated.
