After 12 long years of service at Blizzard, Hearthstone developer Dave Kosak revealed that he will be leaving the studio. The announcement was made via Kosak's personal Twitter account, where he also revealed that his next stop will be at Deviation Games, where he has taken the role of the studio's creative director. It is worth noting that Kosak's departure came a month after Blizzard co-founder Mike Morhaime started a new development studio called Dreamhaven.
Prior to his departure, Kosak recently served as the principal narrative designer of Hearthstone and he spent 11 years working on World of Warcraft, taking on various roles from lead quest designer to lead narrative designer. Now that he has transferred to Deviation Games, Kosak revealed on social media that he is working on a huge project with his new studio. Unfortunately, Kosak didn't go into detail as to what his next project is but assured his followers that "it'll make you go, Woah."
As for what is next for the game after Kosak's departure, it is worth noting that Hearthstone is getting a new mode soon. According to Blizzard, the new game mode is called Duels, and it appears to be a combination of Dungeon Run with PvP competition.
Luckily for players, Duels is a free update, but a paid Heroic Duels will also be available. Apart from the new game mode, Hearthstone is also getting a huge overhaul in its progression system coming to the game on November 12. This update will include a new achievement system, a shakeup quest, an overhaul to the player profile section, and more.
Hearthstone is available now for Android, iOS, and PC.
