Touch of the Grave - does it build threat?

I’d like to ask if anyone happened to check if the passive from Touch of the Grave is actually contributing to threat generation?

My understanding is - as far as I remember the healing had potential to heavily build threat against healers and sometimes make mobs aggro the healers.

I am wondering if this could be utilized as a tank to build additional threat against the pack pull making it some nice addition for tank-oriented forsaken, especially considering this 15s cooldown in recent changes.
