Theorycrafting ARC Tank

Hey, Im thinkin about making a "FaceTank", I do realise there already is a facetank build for witch.
I am trying it out atm.

League Viable (NON-STANDARD // NON-LEGACY ITEMS)

But I want a Arc FaceTank Build and I Would prefer a Witch but Im guessing a Templar would be much better suited..
What acsendancy ive no clue to yet.

Necromancer do have "Mistress of Sacrifice" and with that its easy(easier) to come up to %block cap.
If so Add "Low lvl CWDT with Desecrate+Bone Offering to the GEM Section"

Im thinking a "crit build" but it's not set in stone.

What ive come up with is this so far.. pretty please correct me if you see any fails and so forth.. I need yalls help to make a build out of what ive come up with yet..

I do realise a big part of the game is making your own build and either fail or succeed with it.

But ive spent countless hours trying builds, loads and loads of them..
Spent 1000s of exalteds doing so..

Now I want to try make something out of my thoughts and making it viable both for maps and endgame bosses such shaper/guardians/uber atziri..

Ive only done normal atziri, chimera and minotaur so far (NOT WITH THIS)...

As I would like to one day progress into the Hardcore Servers as I only played HC on d3, I loved it.
Softcore feelt so easy.

I AM NOT SURE WHAT WAY I WILL/SHOULD GO, in the aspect of Life/ES/MoM/LL/Hybrid


Gems:
3L#CWDT Shield Charge+Fortify+FasterAttacks
3L#CWDT Immortal Call+Bloodrage
4L#COH Enfeeble+Conductivity+Arcane Surge
4L#CWDT Tempest Shield+Arcane Surge+IncDuruation
4L#CWDT Spark+Elemental Profiferation+Innervate Support
6L#Arc+Chain+FasterCasting+Controlled Destruction+Onslaught+LightningPenetration+Empower


Could even go 3-4 Curses if I use the passive talent/ascendancy perk/Cospri's Will but I would rather have them as Curse on hit other than a "Curse-Aura".

(lvl1 CWDT + Bloodrage with Immortal Call with Pantheon "Soul of Arakaali +Capture HoT")
Or a CWDT Stone/Light Golem

These gems are NOT a must, its just a thought!

Ive chosen none Auras yet cause If I do go MoM I think I will use a Essence Worm Unset Ring
With either Clarity / Wrath / Discipline / Grace / Haste depending on the rest of the setup.
