One of the missing classes needs to be dex-based, as above, and a few have been asking for a return of the juvenile in the OG Diablo. Due to its age, though, and the way that it's been lost in the shuffle in following classes, a specific"rogue" class would be improbable. Something related to Diablo Gold it remains a possibility, however, according to fan-demanded classes in Diablo 4, the Assassin is pretty high up there and would fill a wonderful function.

A melee-oriented course is possible given that Diablo 4 Barbarian is the only one revealed so far, but for one major reason, it is not likely to be a Crusader, Paladin, or anything of that nature. According to their lore as committed heroes inspired by the heavens and the true decimation of Heaven itself, it is unlikely this specific class comes back. Now, some sort of variant isn't hopeless and a Blackguard at Diablo 4 could be unbelievably interesting however it performed, if it was as an anti-hero seeking revenge or as something truly bad (not seen in Diablo really). Fans shouldn't hold their breath for anything quite like this or the exact opposite character in a Crusader, however.

It could appear to be a perplexing request, but lore-wise, it might be interesting to play an Angel fighting off hordes of demons. The decimation of Heaven might even give itself this manner, but it's not likely to happen at launch, in DLC, or even ever actually for 2 chief reasons.

To begin with, the concept of the franchise is mortals beating allies, and an Angel is obviously not a mortal. The latter may give 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 having a dedicated Healer class and buy Diablo Immortal Gold to do this would include a strange gameplay element to Diablo 4 which is very unnecessary.
