It may appear to be a perplexing request
It may appear to be a perplexing request, but lore-wise, it might be interesting to play with an Angel fighting hordes of Diablo Gold demons. The decimation of Heaven might even lend this way, but it is unlikely to happen at launch, in DLC, or even ever really for two chief reasons.
To begin with, the concept of this franchise is mortals beating allies, and also an Angel is clearly not a mortal. The latter may provide in at some point, as seen between the first two matches, and it’s a large narrative point. Secondly, Diablo has never been a game about needing a committed Healer class and to do this would add a strange gameplay component to Diablo 4 that is very unnecessary.
First, it is well worth mentioning that Diablo Necromancer Necromancer DLC could have been the Druid or even Amazon based on their prevalence at Blizzard. The addition of this Druid here may very well beckon then, making one of the two unannounced classes likely to be the Amazon. It feels exactly the same role as the Demon Hunter efficiently, and may very well take precedence over it. That’s not to mention the Demon Hunter couldn’t arrive afterwards as DLC, only that at launch the signs point in other ways.
Second, the Demon Hunter is iconic with buy Diablo IV Gold Diablo 3 in a way that the Necromancer was for Diablo 2. They had been the exceptional class at the starting 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 exceptional course especially tailored for Diablo 4 will be better off carrying its spot at launching.
