For those who have blocked this passive out of their memories, it's the one that, every 7 seconds, allows you to immobilize an enemy when they are hit with a hatred spending skill.
Obviously it's dead last in every sphere, but...
For Demon Hunters in Hardcore mode:
14 Grenadier 0.71%
15 Thrill of the Hunt 0.49%
Thrill of the Hunt is less popular than a passive that supplies an on-death effect. In Hardcore mode.
That might be something the devs want to consider.
