PoE builds similar to POE 3.27 - 4m pob dps flicker strike woespike test against uber searing exarch + T17 fortress

pob: Hello, I have invested 15+ divines into phys flicker yet am still struggling in juiced high tier stuff(3k+ wips on average). An average map is one to two deaths minimum, struggle to kill the occasional double empowered mob. Getting one shot a lot, especially when molten shell is off. Can someone look over my pob and help? Note this is my first time setting up my own build and going this far with it, any help is appreciated

Came from a Raider build last league, but I felt I died more than I'd like. Did lots of research, and I think I have something viable here, but I'd love some more experienced player's opinions! My goal was to make a Flicker Strike build that's tankier than most, while still getting reasonable damage. The budget was around 10 divines, though I'm sure you could easily add more to get higher stats on the gear. I plan on doing all content with it except ubers, as that would be a whole different build. PoB:

Want to try out Flicker Strike next league so i decided to make myself a flicker strike chieftain, probably as my leaguestarter. I have never played flicker strike before so any advice or feedback is appreciated. Will go for chieftain ascendancy nodes for strikes and melding. Tawhoas seems to be RLY good flicker strike next patch right ? Will probably change into voidforge flicker later on in the league so if anyone has some tips or PoBs for that would be appreciated. My PoB rn:

Berserk unticked because it only activates after taking damage. Don't want to double-dip count 50 rage + berserk for pob numbers/planning. It's in CWDT setup to reduce button clicks / simplify the build. Vaal anc warchief unticked because of short duration, though is used.
