PoE Increased Critical Damage, Spark builds

Hello, I am currently trying to play as aurastacker (first time) and i think i dont understand mechanics, because when i watch streams highlights, many ppl got much better dmg and surviveability with worse gear, what am I doing wrong? In maps i die often to multiple hits, 88% all res, 30k armor and 30k evasion and i feel like paper. Is there any way to fix it "cheaply"? What would be next big upgrade? (I know Voices 3p, what else?) Thanks for help in advance.

I made this build over several hours and there are so many things I changed and tried to make it better. I hope some of you have ideas how I could improve this build or if I missed something obvious. The gear is already pretty juicy, but I know how to craft them. At the moment I'm not satisfied with physical defense. I tried to reach some good amount of block and armour, but i cannot do it while mantaining enough omniscience. Thank you for looking into this build!

Playstyle < Clear: Just spark pretty much, for rares etc you can drop orb of storms and stand inside it to do more damage, marking it will make it take more damage Bossing: You want to use Orb of Storms for extra damage, we have lots of utility like Sigil of Power and frost shield that will make it better to stand still against bosses so we have lots of damage and extra mitigation inside the circle. Orb of storms doesnt have a duration now which makes it really nice for bosses, you only have to recast it when it expires You could pretty easy switch this build to ball lightning an

TL;TR 100% lightning to chaos with phantasmal spark and voltaxic rift, hierophant mana based build with archmage, 50-60% MoM, agnostic, lots of mana regen, lots of fun. Pros: high eHP (8.7k), high life &amp; mana regen, 100% chaos damage Cons: prone to oneshots (low life pool), res hungry (cuz of uniques) &amp;x200B; I didn't play (vaal) valtaxic spark when it was popular (some time ago) so I decided to try to make one now that it isn't as powerful/viable (I'm smort). First, phantasmal spark gives 40% lightning to chaos conversion, combined with Voltaxic rift you get 100% lightning to

Replica maloneys would be an easy way to sustain fanaticism (if it counts as you attacking). Other ascendancy options did not get added so damage could change. &amp;x200B; Here is a POB of a build that utilizes templar. It's expensive, but it also shows the potential. I only included battle mage by changing voltaxic rift damage to spells damage. If Replica Maloneys triggers fanatics, this would be an excellent option.
