Fire Elemental Discharge Templar;

Hey guys, i was theorycrafting about an "elemental templar" and i find one build kinda...very powerfull. Its based on Discharge (Endurance Charges).
First the skill tree:

The skills idea its ->



Discharge with Increase AOE - Added Lightning Damage (Shock) - Item Rarity - Item Quantity.

Enduring Cry with Increase AOE - Faster Casting.

Determination with Mana Reduce.

Purity with Mana Reduce.

Infernal Blow (For single target if needed) with Faster Attacks - ADD Lightning Damage - Life Leech - Mana Leech

Shield Charge (More used for mobility) with ?

Shield Charge can be changed for Phase Walk, maybe? The ideia its running throug MANY mobs, using enduring cry, then discharge. Determination with Purity for more tankie, cuz u gonna take ALOT of hits prob. I used alot of elemental dmg nodes cuz i think its a BURST for this skill that uses only fire damage as main damage source.
Pretend to use Chain itens (Armor+ES).
Dont know if im right, or if im wrong...opinions please?
First time trying to make a build, so...dont hate me! :P

Thanks for your time, and please...come help me build an cool Templar!

Sorry about my bad english, tryin to learn more and more. :)

very interesting but lets say you facing a rare mob with life leach + life regen how the hell are you gona kill it ?
your single target dps output is so low that the mob will just regen life and slowly drain all your pots you will be forced to run away xD
