Build Help (Inquisitor CoC Cyclone/Purifying Flames)

I'm looking for help with a build idea, since most of my builds just don't work end-game. Anyone interested in helping out, check out the bullet points below.

Staff CoC Cyclone/Purifying Flames.

* One of the updated weapons with this 2-Hand league is a staff that has 100% Global Crit chance.
* There are also quite a few crit chance staff nodes in the tree. (Smashing Strikes, Counterweight, Blunt Trauma, Serpent Stance)
* Consecrated Ground synergies with Inq Ascendancy and possibly Zealot's Oath
* Only 2 uniques that I can see as necessary (Loreweave and Gifts from Above)
* Divine Fury notable feeds right into this build
* Magmatic Strikes takes Purifying Flames from 50% to 90% conversion
* Easy access to Unwavering Stance (Since cyclone doesn't give stun immune anymore)

Building it myself in the Community Fork PoB I was able to get it to:
70% crit on the Cyclone (No temporary buffs)
91% hit chance
Part of my problem is the defenses. It seems like going Zealot's Oath and the Pious Path ascendancy wants it to be an ES build, and I just couldn't get my ES that high.
I built rare items in the program, using the half stats it started with. Besides the 2 uniques, only the staff itself was potentially hard to find.

I think this build could be fun and interesting; I just don't know how viable it would be. Any help is greatly appreciated.
