Looking for opinions about my CI "aura" spectre theorycraft.

Right now I'm playing a life-based SO spectre build and want to transition into something more highend, I made this pob but honestly unsure if it's worth going for because most likely crafting and acquiring all gear would be done in 50ex, which is all my currency.

Issues I'm aware of:

-mediocore dps, but my current version has exactly half that dps and did all content with relative ease

-minimal physical dr, tho I don't think there is too many scary endgame physical damage to be that scared of

-low es, haven't figured a way to fix it

Also I aimed for high-survivability through 89% res and high regen. I'm aware of the popular ci spectre builds going around but those are extremely glass cannon-like which i really dont like.
