I'm not sure why they would nerf the burn to nothing then add in an Artefact to reduce burns in PvP. It's like watching a ball fall on someones head *clunk* then saying "Heads!".
Also no one is using that artifact. I have litterally never seen it in crucible.
I use it sometimes, works great for those pesky nightstalkers
No need. Who wants to use something that reduces burn from 2 to 1.
