PoE skrillex builds

is my build, I am not a PoB warrior so my calculations are probably off. Are there any glaringly obvious issues I have in my build, maybe more efficient pathing in the passive tree, or gear choices that aren't working? I just tried Maven and I made it to phase 3 but it felt i wasn't pumping enough damage to safely move through the fight before the floor was completely covered. I know there is a skill issue there but I tried to overlap the floor as much as possible, the fight was just going on for a while. Mostly looking at triage of gear to change, maybe link
