Low DPS with dual strike

Hi everyone ! Im kinda new to poe and im trying this build :https://pobb.in/LPRZ3adcybEg

I played Boneshatter before buying some of the stuff (paradoxia, Alberton replicas, eternal damnation and the balance of terror)

But I now I made the switch and I do less damage than boneshatter. I know some my gear miss strength, but I wanted to know if I missed something else? Thank you!
