Help with 3.23 Autobomber Slayer please

Need some eyes on my setup. Map clears pretty well, but boss damage seems off. I basically copied everything almost even down to the exact gear from Phoenix's 3.23 autobomber update https://www.youtube.com/watch?v=BMMGoVTdGyA&t=154s

I skills gems may still need some work.. but I definitely feel im missing something. Other then lvl 92 vs 100, idk where to look. I see a big difference in crit rate. I am not adjusting anything in PoB, other then including skills in fulldps.

My current build: https://pobb.in/4E5Kwv5zFG6L

Phoenixs build: https://pobb.in/DmJilKMs451A

It could be my execution of the build. I know this is based off Palsteron's original build and he had a single target dps setup using a different weapon and gem swapping, so im not sure if Phoenix did something different.

Appreciate all feedback.
