PoE Witch, Bow builds

Hey guys, I have been playing this build since start of the league. Since i got bored with it, and wanted to do some Ubers or to be more fast, what changes would you do in my place? I'm open to new build suggestions. My budget is around 110 div + everything from this build POB:

PoB for context: Up to about 20 div now and need to decide whether to invest further into EA or pivot. I like the speedy map clear of EA and bossing feels really safe since I just place totems and dodge around. That said I don't love the damage delay on EA and it can sometimes feel a bit clunky. I've been eyeing impending doom and also considering EK ignite or vortex ignite but I'm not really sure if these would really be improvements over my current state. I don't want to do a respec into a build that can't complete the content I'

So I'm still working on Chaos Res and Spell Suppression but I'm comparing my DPS to other PoB's and I don't understand why my DPS is so weak compared to them. Right now I have 8 Divines that I can use for upgrades but everything I'm looking at either cost more the 8 or is only a 3% upgrade according to the PoB "Trade For These Items" weighings . So I'm not sure what I can do from here.

I ran this build as my league starter in 3.17 when ashes was easy to get, I loved the clear speed I got from this as well as how tanky it felt vs bosses so I farmed a lot of uber elders with it, not really invincible but with divine flesh and few phys damage reduction sources not much could one shot it at that time. I kinda wanna do the same build for my second or third build for this league with new Vaal Caustic arrow but not sure how meta has changed and what is new, skipped most of Sentinel and Kaladnra leagues. I could not find all the gear pieces that i used but missing ones were nothing

Current latest updated pob: (Thanks to bodelotte for the suggestions/improvements!) Above is what I have so far. I love storm rain, but it's not ideal for me for mapping. With the new Voltaxic Rift 100% lightning -> chaos conversion, occultist becomes interesting. This means profane bloom could help solve some of the mapping issues for me. I have never made a build however, most of the times I just follow someone elses guide and change it a bit. I thought maybe
