I was playing around with the pet intensity calculator, and compared two different banes I had seen. The first was 60% intensity and the second 77% intensity.
I built them identical in the planner, and the only difference was the 77% bane had only 7 more HPR, that’s it. So, in my opinion, don’t get too wrapped around the numbers until you take a good look at the banes being offered and the prices people are selling them for.
