3.19 Galvanic Field + Divine Ire Juggernaut / Shock and Mana questions

Hey,

https://pastebin.com/S784yu2W

I don't know anything regarding shock and mana management and would like your knowledge on this PoB please!

In which content will Divine with overcharge Ire be able to inflict max shock (65%)?

Will I have mana problems? 73 unreserved mana with arcane surge and 36mana regen.
Or should I try a Lifetap on Divine Ire at least?

Is 55k armor be enough to tank lightning DOT and the lightning guys running toward me?

Would gladly appreciate some help before losing time leveling an alt if basic knowledge tells that is is not viable :).

Thanks have a nice weekend.

https://pastebin.com/sZJKJ5Gd changed some stuff based on preference, wrath seems to be more damage than zealotry , assassins mark doesnt do much i changed it to enfeeble for bosses and rares , picked up some jewels i thought you were missing . I really dont think arcane surge will be enough , enduring mana flasks are okay , you can get to eldritch battery and pick an elemental mastery for dmg leeched as energy shield . Worst case scenario you change inspiration to lifetap . Lightning DOTs arent affected by armour because they arent hits and they will kill you , thats the major problem with doryanis
