Along with the many changes we announced for patch 2.3 we also just mentioned that there will be significant adjustments to the Hellfire event:
06/24/2015 02:12 PMPosted by Travis DayThis is a very large patch so we were unable to fit ALL the awesome changes into the preview blog. There are changes to the Hellfire event structure coming in the next patch. Keywardens will now directly drop Infernal Machines instead of Keys and the Hellfire Amulet now has a socket built in.
Check them out once they hit ptr and let us know what you all think! =)
