Crazy tanky build V2, I'm back again, any more feedback?

Hey guys, previous post here https://old.reddit.com/r/PathOfExileBuilds/comments/mtrgtl/crazy_tanky_build_need_help_finding_even_more/

My new PoB! https://pastebin.com/bFJD5dNp

Since that post, I've gotten some feedback, and now the build clears even better, and has more damage! You can see that I've been collecting a few items for the post (based on the item names, New Item is theoretical), but I'm still in white tier maps after sitting in PoB so long haha, I'm sure some of you can relate.

So, the build: The entire build is now Crit, and can hit 5mil slams on Shaper (how below). 85% fire, 89% Chaos, 20-35% phys taken as fire. Body armour with extra curse (phys taken as fire extra later) for both curse on hit rings. Mark gives frenzies, PCoC supporting Infernal Cry's explosions gives Power charge uptime on bosses, frenzy uptime comes with the Mob Mentality uptime RNG.
Also, Alt quality Tectonic slam for leech instead of Chieftan node, and cluster node takes care of mana.

How to one shot map boss: 1-Get seismic cry down to final exert
2-Use tectonic on air until next slam removes a charge
3-Patiently warcry the air (or run around boss if possible to speed process up) until you get full power and frenzy.
4-Run up to boss and use vaal totem. THEN get hit (Can be adjusted). Boss knowledge of incoming damage helps.
5-This triggers Wave and Phase Run, then slam immediately.

Anyways the clear with Infernal cry explosions and ignite prolif, and Tectonic slam's AoE, should be fine.
I've included an 8c rapier I bought, similar stats but not double damage, so, less but still doable.

What do you guys think??
