Speculation is Diablo IV Gold running rampant across the community as to what these might be, and practically every former class in the series (as well as a few new ones) has been theorized about so far. It's nice the wisest move to put all the eggs in one basket yet, but for those wanting a stylish spellcaster, Sorceress is a good bet.
New information regarding Diablo 4 is likely months away, with the next obvious time for it being BlizzConline in 2021. That hasn't stopped fans from debating and speculating, though. A recent aggregate poll tallied a bunch of votes from the community, particularly on classes that fans wanted.
On it were some obvious points, like how Necromancer is the most demanded Diablo 4 class alongside the Amazon, but there were often odd requests: classes that didn't exists, races that didn't make sense, and quite often, a dedicated Healer class request.
Now, that may be an odd request to some. It doesn't really fit the playstyle of any of the Diablo games, but those who want it make a few compelling points. With that in mind, here's just a few arguments for and against Diablo 4 having a dedicated healing class.
