Frost Blades advice needed

Hello!

I've been trying to convert Sidefx Frost Blades build for Shadow class. I know Raider is best for the role but I'm just simply obsessed with dual claw shadow builds XD

IMPORTANT: I'm no good at making builds so please go easy on me, I know I make a lot of mistakes ^^;

So after messing a bit with PoB this is the result: https://pastebin.com/cwcifsnP

What I did: (not much, really)
+ twinked the gear to focus on DPS, resulting in over 2xDPS of the original (I have like half the stuff mentioned in the Items section, but I had to sell one Taming once, but since then I made the chaos back. Wondering if I should re-buy it)
- it killed HP pool down to 3.4k... But somehow resists remain capped.

* swapped Raider to Trickster
+/- with Swift Killer I honestly don't feel any difference with generating frenzy charges, but as a bonus I also get a ton of power ones
- no Phasing and 40% increased ele. damage
+/- I can get Onslaught from abyss jewel

PS: Original, only swapped Raider for Trickster: https://pastebin.com/WDuEP98c

I used these builds to level both Raider and Trickster, and somehow I feel like my Shadow version levelled a lot faster compared to Raider. But maybe it's because Shadow's starting point is so close to claw nodes. Once I filled those in my clear speed skyrocketed. (I made it from lv 1 to 54 in ~8 hours which for me is really fast since I like to complete every map I'm in, deathless so far)

At this moment I'm getting the second jewel socket and then I'm focusing on HP nodes.

My question/request is:
1) Could you help me arrange the points/items to get the best survivability-DPS balance? I don't expect the Shadow version to be as powerful as Raider, but who knows, maybe we'll find a way.
2) With Trickster ascendancy I'm wavering between choosing Weave the Arcane and Walk the Aether. While the first one gives better defenses, the second provides better DPS since I'm zooming around with Whirling Blades all the time...
3) Do I need that Vaal Pact node?

That's all the questions I have so far.

Let's make dual claw Shadow great again!

I might be late to giving my opinions, but here you go :

1. I have tried to go Trickster and hoping to get same results like Raider, ended up i got more damage (before frenzy buff) but alot less life. No matter how i tried that, its hard to get the same results like Raider build.

2. Since Trickster is buffed, it's clear that you always wanted : Swift Killer, Weave the Arcane and Harness the void. Not sure for the last, because nothing really benefit FB build, i think 2 small nodes are better.

3. If you are using Claw nodes (Soul Rakes) also taking blood drinker, i think you will be fine without VP.
