Optimising a Shockwave Totem Hierophant (theorycraft)

A few weeks a go I was theorizing what I wanted to play for the next league, and I made this thread: https://dd.reddit.com/r/PathOfExileBuilds/comments/140biuw/how_to_build_a_tanky_allrounder_with_shockwave/

I had a set or requirements for the build, mainly a totem playstyle, high quality of life, and zero-to-hero possibility in terms of scaling. Eventually I landed on Hierophant as an ascendancy, simply because it provides the most straightforward access to damage and totem placement speed, and because it has a good position on the passive tree. This allows me to focus more gear into defense compared to more 'naturally defensive' options such as Scion.

My planned endgame setup is this: https://pobb.in/K8G1VhvCDPF7

At an expected investment level of around 400-600 divines, this pob has:

• 100M DPS
• 88% Max res
• 100% Spell Suppression
• 38k Armour
• 180% Movement Speed

And useful secondary stats, such as:

• 1k Life Regeneration, 30% Recoup
• Stun Jewel-based hit defense
• Mageblood-empowered resistance flasks
• 4 Endurance Charges
• Permanent Freeze on basically everything

Some things I have not yet completely solved, such as the exact Int + Str balance for Rational Doctrine, and a good way to craft a Shaper shield (the best I can come up with is spamming spellcrit essences until I hit 2 good suffixes).

That said, I'm pretty happy with what I've thought of so far, and I was wondering if anyone could provide feedback on my choices. Do you see any areas of improvement, or issues with the build? I would love to discuss any part of this, whether it comes to how to craft, the passive tree, or gear choices.
