Essence extractor bug or working as intended?

The essence extractor trinket (‘your attacks have a chance to drain [x] health from your target and heal you for 50% of the health drained.’), which is a reward from a daily WQ in, Revendreth today, I believe (?)… is this bugged? No where in the trinket or the effect itself is it documented this is only for ranged classes as far as I could find in my search, however I read comments suggesting this.

If that’s the case, is this a bug? If not, that’s really too bad, because Tanks could get some good use out of this!

I used to have it on my prot pally and it proc’ed correctly.

Ok so it actually worked for you well?

Yes, the healing amount is tiny though.
