I dont think you guys are even thinking about the items required and the OBJ of ball lightning spec. The OBJ was to gain perma immunity with SS however, blizzard reworked that skill.
Damage wise you need both meticulous (obvious choice for cubing) and rucksack. You automatically loose damage because you cannot cube an actual weapon. Next you are forced to used Kridershot. Kridershot isn't a bad weapon at its core , but lack multiplier damage.
With the past nerf to helltrapper this build is dead for any progression
With a nerf to Crowd Control, ball lightning has a very long start up time. Multishot and chakram can kill 50% faster. Cluster arrow 100% faster.
I have already tested ball lightning with marauder's set. So far, it's not cool. With weak items, i mean the proper items but not ancient, i'm dealing about 200mil crit per tick and every turret is dealing about 20mil crit.
Now i am going to try it with unhallowed essence.
Looking forward to hear it with UE
and ty for sharing
