PoE Archmage, Ball Lightning, Fire builds

Discharge changes from patch notes: Now has an added damage effectiveness of 450%. Now deals 56 to 203 base lightning damage per power charge removed at gem level 1, up to 394 to 1422 base lightning damage at gem level 20. Now deals 30% less damage with Ailments. Despite the 30% less damage from ignite, the added damage effectiveness seems to me like this will be the strongest skill for ignites. So I threw together a build with medium-budget items and it turns out to deal decent damage. Clearing might be a pain due to the cooldown and reliance on secondary spells for charges, though.
