PoE Boneshatter, willalalala builds

Hi, I haven been playing POE for a while but never dived too deep into the game. This league I looked up some boneshatter jugg builds and decided to try that for the first time. my build: I have a few problems/questions with the build and wondering if someone can help me with it. &x200B; 1, Damage: I seem to be clearing maps alright, but I think with the league mechanics, some rares and uniques do take a while to kill. Outside of making boneshatter 6L and get a better weapon, is there any other things I can improve my output?
