Where to go from here on ele hit deadeye build?

Here is the Pastebin, https://pastebin.com/hi5jPNpZ

This is the current skeleton of the build.

In its current state, its 153% life, grace, determination, defiance banner, petrified blood and ghost shroud for defences

Offense is based on snipers mark elehit with wands, relying on split from the mark as well as the deadeye chain and extra proj for clear. Ele hit also has the built in explosions which should help.

Single target with a geared out character is probably at least 500k sDPS but there is a lot of scalability with larger budgets

Right now the tree is set up for minimal reliance on gear, but there are a lot of obvious upgrades, such as

Crown of eyes, the interrogation/skitterbots, cluster jewels, int stacking, vaal pact, the missed jewel nodes on the tree

If I had to guess, the build is probably a little weak to one shots but ghost shroud should help with that.

I am considering running this build in the delve event, but I think it may be a little squishy.

Should I be looking at getting some more defensive layers, like leaning into block and/or spell suppression, maybe max ele res?

Or should I be looking into more damage at this point? It seems like enough, but I could definitely be wrong, especially since delve will have much less ability for Far Shot to scale damage due to confines.

What do you guys think? Where should I go from here?
