One commonly requested course for Diablo 3, Diablo 4, and Diablo Gold elsewhere is the"Angel," or at least, a"healer." It may seem like a confusing request, however lore-wise, it would be intriguing to play an Angel fighting hordes of demons. The decimation of Heaven might even give itself this manner, but it's unlikely to happen at launch, in DLC, or even ever actually for two main reasons.
To begin with, the concept of this franchise is mortals overcoming demons, and an Angel is obviously not a mortal. The latter may provide in at some stage, as seen between the first two games, and it is a large storyline point. Secondly, Diablo has never been a game about needing a committed Healer course and to do this would add a strange gameplay element to Diablo 4 which is very unnecessary.
First, it is well worth mentioning that Diablo 3's Necromancer DLC could have been the Druid or even Amazon according to their popularity at Blizzard. It feels exactly the same role as the Demon Hunter efficiently, and might well take precedence over it. That's not to mention the Demon Hunter couldn't come afterwards as DLC, only that at launching the signs point in other ways.
They were the unique course in the beginning line-up, combined with a few standard array classes. As such, not only does the Demon Hunter seem more like DLC for Diablo 4 than anything else, a unique class especially tailored to Diablo 4 will be better off taking its spot at launching.
It's just a couple of months before Blizzconline, and https://www.voidk.com/ in the time, at least one of the remaining two classes could hopefully be revealed.
