Shield Crush Jugg w/ 400k Armour Theorycrafting?

So I hate dying and tried to come up with a gigatank build:

https://pobb.in/nzgfxATivkng

DISCLAIMER: I HAVE NOT PLAYED THIS BUILD THIS IS ONLY THEORYCRAFTING

Defences:

• 87/85/85/75 Resists
• 8 Endurance Charges
• 444k Armour with flasks up (They have 90% uptime while hitting stuff even on bosses if you can keep hitting em)

This can theoretically tank sirus meteor without molten shell and memory game with molten shell thanks to the new warden ascendancy (however shaper ball deals almost as much dmg as sirus meteor lol)

As for dmg we have 15.5m dps with 2 overlaps and temporary buffs up (Blood Rage, Ancestral Protector and max brutal charges, which you'll have to build up by getting hit every so often, but no berserk) and we can scale it higher with forbidden jewels, a better shako, a +1 endu ralakesh etc.

It should also be pretty cheap:

• 10c for Replica Dreamfeather
• 50c for a perfect Emperor's Vigilance (there was a 98% one for 10c)
• I bought the shako for 40c, however there are many gem combinations that are useful
• 1 div for a 4.3k armour +5% all max res brass dome (no need to 6 link)
• res glove and rings, optionally some offensive modifiers
• A high quality roll Ashes, 2 div
• Ralakesh is 15c
• Arn's anguish was 10c
• TWWT and Transcendent Flesh are 150c but they can be replaced with rares or other rolls
• Other jewels are below 10c each
• 10c for tincture with all freeze and rage gen

I plan on leveling this build soon so any thoughts on this before I start and realize I overlooked something?
