Bloodless

I've been looking through the Forum, and still wondering what the point of Bloodless is? Why have it even on the Tree, if having it allocated is Negated?

"

it allocated is Negated?

What do you mean exactly?

I think you are talking about enemies can not leech from you, but what is negating it?

(Edit: There is a recent post about this on the bug reports forum, https://www.pathofexile.com/forum/view-thread/3736644
Unsure if it is a bug or a mechanical question, but it does appear some other people are questioning if it is working. Perhaps providing more information or evidence may help get it resolved.)
