Confirmed in the newest 5.2 PTR Patch notes:
Interesting turn of events. As they've stated, the playerbase (rightfully so, IMHO) took the words "head enchantment" a bit too literally when the notes were released, but I cannot be the only one who is surprised at this being the change they are intending. How will this interact with the Sha-touched Weapons? How is this a part of the overall Legendary theme? I know that nobody here has any answers as of yet, but I'm curious as to what you all think.Along the way, they'll unlock the secrets to a new legendary metagem, Crown of the Heavens.
