Something I’ve noticed consistently in the original build and in many of the theorycrafts is too many points in Fighting Form. Fighting Form gives nothing to this build (unless you change it to be a bleed build), except for passthrough on the 3rd cadence hit, and it gives you that with only 4 points.
The game tells you it gives 51% chance at 4 points, as does grimtools, but ingame, you get passthrough every time at only 4 points.
