PoE Blade Vortex, Slayer, Cold builds

I have been playing Wild Strike in the past and always had a blast. This league i want to give it another go with this build i made. I was prety shocked by the Voidforge prices though, so i guess i won't leaguestart with this. I'm unsure whether i should go with Grace or Determination. I also don't really know what other skills i should use so i made a CWDT Blade Vortex thingy to create power charges. Feel free to give me some suggestions

So, i changed some gems, some items and recrafted my sword with a close to perfect tree on it. Also ditched the astral projector. Discharge becomes to strong and with astral you kill stuff before you flicker to it. Kind of a weird play style as it auto targets everything but it bricks flickerstrike movement. Also ditched multistrike and faster attacks. With blood dance its possible to get our attack speed very close to 3.78 attacks per second. No need to aim for multiples of that. Pob: Flicker trigger discharge Dps of the pob is wrong as it doesnt account for
