was it nerfed? I haven't seen a fuggin heart in like 2 days lol.

There was no mention of a nerf to the malignant hearts.
Are you running whispers to find them in caches?

If it was nerfed, it was a ninja nerf.

I am about 8/10/16 and 0 hearts. Unless I am missing something on where I should be getting hearts? There is a clear imbalance. And no, I have not been crafting hearts into the other limbs.

After the world boss, legion events and completed whisper dungeons look for an icon on the mini-map/red circle on the ground. If you don't stand in it within a few seconds it will disappear, if you do then a easy elite spawns and drops a body part - in my experience so far it's a high chance of heart.

Doesn't always appear and sometimes there's multiple, I've also seen them in blood zones.
