Prophecy Hardcore Blade Vortex occultist - which ascendancy nodes?

Hey guys,

I need your help, I havent been playing for a while and Im rather noob than anything else. Im using non crit blade vortex as I just love this skill. The only unique I will use is the below since it gives me 100% uptime of unholy rage and keeps my power charges up and enables the possibility to use leap slam+fortify for just one chaos.



My witch is 56 at the moment, hybrib life/es but I plan to switch to CI soon. I will focus on getting as much chaos damage as possible and abuse the void beacon ascendancy node. Now I wonder which ascendancy nodes you would recommend as I read that vile bastion is not good. After normal lab I chose wicked ward since it gives me quite a nice defensive bonus. Any recommendations which ascandency nodes to pick are very welcome.

Below my skilltree



thx
