PoE Blade Vortex, Slayer, Chaining 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
