Shock Nova Hierophant (no Archmage)

Hi, so I've been tinkering in PoB and figured out I will make use of new Shock Nova and Sanctuary of Thought having 25% MRE (since 15% MRE mastery was gutted), here's PoB:

Perks of the build:
~5.5k life
84%/78% block with Glancing blows (overcap is useful for less block chance maps)
Aegis Aurora with a good amount of ES
30k armour before flasks
Auras: Determination, Wrath, Tempest Shield, Vitality, Precision and Zealotry on Divine blessing (50% less mana cost of skills from Sanctuary of Thoughts, Tireless cluster and alternate qualities on Inc duration/Divine blessing let us use it with 24 seconds uptime if using Mana reservation mastery for 50% increased duration also could fit in Defiance banner with the alternate gems)
70% reduced curse effect (curse reduction suffix on a flask makes us curse immune)
fairly cheap in my opinion since the only mandatory item is the shield, everything else is your choice
Maligaro's Virtuosity gloves let us not care about Crit multi and focus solely on Crit chance which we can obtain 100% fairly easy.

Let me know what you think about it/what would you change/add.
Cheers.
