The network has a lot of rumors about the new hero Diablo 3 immediately after Blizzard posted a vacancy for "Senior technical artist of characters" on the official website.
The company requires an experienced person who has been working in this position for at least three years and with the following skills:
Create character sets that will help set the bar for quality and efficiency.
Experience in creating characters, tools, and technical workflows.
At least 3 years of experience creating equipment for characters in Maya.
Thus, perhaps until the release of the fourth part, Blizzard will continue to support Diablo 3 not only with seasons, but also with new content, in particular, characters. If this is the case, then most likely we are waiting for a separate DLC, such as with the Necromancer.
It is worth noting that now the game has seven characters to choose from and to play for.
