Self-cast Discharge :thonking: ? Would love some some ideas and critique

So discharge will receive a large damage buff, but will be on a cooldown.

I'm thinking about ways to make self-casting Discharge work, and i've come up with some archetypes, although none of them feel 100% satisfying.

First i thought of an Archmage build to make use of the fact that Discharge now is on a cooldown anyways, so handling the mana cost would be a lot easier. Here is my pastebin for an Occultist Archmage build:

The Problem with Occultist Archmage is the fact that while Forbidden Power does reliably generate charges with Archmage, it only generates one charge at a time due to its wording. Another problem is that Discharge is a "hit once, and hit hard" skill, and these don't profit from Archmage that much.

Another archetype would be either Jugg or Chieftain fire-based Discharge, probably using the large hit to inflict huge ignites. I'm not very used to ignite scaling so i could really use some help here, since i've not really gotten the damage to scale properly (obviously the new Discharge would deal WAY more damage)

I'm not sure if i set that up correctly, due to orb of storms only dealing lightning damage with elemental equilibrium, the enemy sould have their fire resistance lowered when i hit with Discharge, right?

I realize the damage numbers are all out of whack anyways, since we don't have the new gem info yet, but i'm just hyped and would love some ideas on the concept, and if you guys think it's viable.
