NOTE: 
Boundless Unstable Currents kind of throws all of this Hoobla into the trashcan because it allows you to pick up crackling energy beyond the cap. Therefore expenditure rate doesn't matter. Which sort of makes this entire section bleh. Just aim for 94.4% attack speed, make it simple. Updates to this (as attack speed is important coming shortly).
Now why would attack speed be something so important in this build when we could just have another Damage Multiplier?
Well this is because having more attack speed replacing something that deals more damage doesn't mean we are doing less damage over time. It means we are doing less damage per hit, but more hits in the SAME TIME PERIOD.
Basic Concept of Slow/Big Damage vs. Fast/Small Damage
For Example: Assume 2 situations
Situation 1: 100 damage / 1 hit per second = 100 x 1 = 100 Damage per Second
Situation 2: 50 Damage / 2 hits per second = 50 x 2 = 100 Damage per Second
^ Even though in one instance we are dealing only 50% of the damage, we are still dealing the same damage over time due to attacking faster.
Application for Build
In the case for our build, the reason why it is so important to attack faster is based off how much crackling energy we can collect and expend.
Crackling Energy does not have a limit to How Fast You Can Pick It Up. But it does have a limit to how fast you can create it and expend it.
CREATION - If you can only create 10 Crackling energy in 10 seconds, then that's all you can expend within that 10 second periodEXPENDITURE - If there is 100 Crackling Energy on the ground, but you can only hold a maximum of 10 crackling energy; then you can only pick up more based on how fast you expend the crackling energy. In this situation, if you can only expend 1 crackling energy per second, then in a 10 second period you can only expend 10 crackling energy
So how does attack speed solve both the problems for CREATION and EXPENDITURE?
Attacking Faster with Boundless Unstable Currents will create more crackling energy through Lucky Hit Chance, but it will also create more crackling energy by casting 
Crackling Energy Ball Lightning and 
Critical Strike Chance Chain Lightning randomly as you keep casting 
Static Field Blizzard. Therefore by attacking faster, we generate much more crackling energy. This helps with solving the CREATION problem.To solve the EXPENDITURE problem, 
Esadora's Overflowing Cameo increases the rate by which we discharge crackling energy which directly scales with our Attack Speed. This means the more attack speed we have, the faster we can expend the crackling energy, which then allows us to pick up more crackling energy per second because we are not consistently capped at maximum crackling energy charges.
What happens when we solve the Problems for CREATION and EXPENDITURE.
Because energy charges are being expended faster and hitting targets more frequently, we now lower the cooldown of 
Unstable Currents through the use of Esadora's Overflowing Cameo. This is powerful as Boundless Unstable Currents and 
Aspect of Armageddon synergize to give an enormous damage multiplier.Because we are rarely capped at the crackling energy limit due to the tick rate of crackling energy being effected by increases in Attack Speed in tandem with Esadora's Overflowing Cameo, we now pick up much more crackling energy per second. Every time we do this, we increase our damage due to Boundless Unstable Currents.
How Much Attack Speed Do I Need?
That is completely up to you, but my recommendation is to try to aim for at least 94.4% Attack Speed. This will allow you to attack 2.4 times a second and drastically increase your crackling energy CREATION and EXPENDITURE rate.
