Lightning Rod is still disgusting

Lightning Rod got a buff this patch, but they made it so only Lightning arrow can proc the explosions. By having a second lightning arrow or swapping 1 gem in the main lightning arrow setup we can proc lightning rod to absurd levels. The main projectile from LA cant chain but the beams do chain, and chain support adds +1 chains and doubles the amount of chains. I dont know exactly how many times im proccing Rod per cast of LA, but its a lot. This character has a basic duañstring bow and the rest of the gear is bad. Rod is on a 4l with conc, primal and infusion.

Barrage has a lower cd too, and rod only benefits from hitting more often so spamming that skill brings a lot of additional damage for the rods.

Rod seems very busted still, at least at my gear level (level 81 deadeye with 2 ascendancies only and bad gear)

Thoughts?
