You mean that the Lightning Orb pierces through enemies while traveling (instead of being thrown in an arc) and it shoots lightnings while it travels?
That sounds awesome!
I also thought about that it would be cool if it could work like the BFG 9000 from DOOM 2016 and Eternal.
It could shoot like x Chain Lightnings per tick one after the other while it travels and the Chain Lightnings jump to 2 additional targets as well.
The lightning orb you release from the Storm Chaser rune from Energy Twister looks a lot more like the lightning orb from the Spark rune for Arcane Orb should look like, imo, both for Spark as well for a rework of Arcane Orb.

Yeah, it is pretty useless at the moment.
In the next patch or with a rework the damage should be increased as well (or FO’s could get reduced).
