Players voted on which class they would like to see in the game, but Blizzard has its own opinion on this matter.
While much remains unknown about Diablo 4, there is constant talk about one of the most important aspects of the game - game classes. Many fans are hoping to see something new in Diablo 4, while others want the most classic classes.
A recent data gathering brought together several surveys about classes in Diablo 4 from around the web, to identify the most popular. There are some interesting things here, like the steady demand for something new or for the return of some Diablo 1 classes, but in the end it turned out that the most popular class is the least likely to make it to the base game.
Three classes have been confirmed so far: barbarian, Druid и enchantress. This means that already added characters focused on hand-to-hand combat, as well as two classes of magicians (casters). Amazon seems like a framework to give players a class based on agility while another melee class - whether it be Paladin or not - it looks like it will complete the base five.
Therefore, most likely we will not see the Necromancer again with the release of the game. Many fans were outraged and disappointed when the developers added Nekra to Diablo 3, but only for donation, as a separate DLS. What does it cost then as half the cost of the original game.
Necromancer is classified as one of the magicians, so he will definitely not be added to the 3rd. But Bliz realized that since the people voted for him, so it will be possible to cut down money again and sell the most popular class along with DLS. Many fans are outraged by such measures, but the chances that Blizzard will listen to them are minimal.
