What do Necromancers, an updated OR14 unit and Abed from Community have in common?
Soon, they'll all be a part of the Blizzard universe, one way or another.
The Necromancer class for Diablo 3 is set for release in "the second half of 2017". The blog post on Battle.net showed off all the skills you'd normally associate with a Necromancer: a Grim Scythe, a Death Nova, Blood Golem and so on.
The Necromancer will not be a part of an expansion pack, but rather a content pack which will feature "the class, an in-game pet, cosmetic wings, two additional character slots, two additional stash tabs (on PC), a portrait frame, pennant, banner, and a banner sigil." It will, however, launch together with a content patch, which will add a couple of new zones, Challenge Rifts .
