Raekor Slam: Calculator comparison of Immortal Kings vs Ignore Pain

https://www.d3planner.com/191938177

I decided to do a little theoretical comparison before making a significant change to the build I’m using. So I used d3planner to create sets of all Primal gear as ideal examples for comparison. I wanted to see how much of a damage difference there would be between using the Immortal Kings set and Ignore Pain. I focused specifically on the damage per Seismic Slam since that should be the most useful at indicating the actual damage of the build. Am I missing anything here? The biggest caveat I can think of is the amulet choice. Substituting in a Hellfire Amulet could open up using the Rampage passive with the Ignore Pain version.
