Blizzard announced that it is dramatically scaling down development on Heroes of the Storm by shifting developers away from the game and also shutting down the Heroes Global Championship 2019 esports season.
In a set of two separate blog posts Blizzard announced changes to its Blizzard-themed MOBA. First, newly-minted Blizzard CEO J. Allen Brack announced that development on Heroes of the Storm will slow and that some developers will be moved to other projects, including some unannounced games. Development on Heroes of the Storm will continue, but at a likely slower pace.
Secondly the Heroes Global Championship, which is the sole esports league dedicated to Heroes of the Storm, will not return for a 2019 season. Taken with the news of the game's slowed development this likely signals the end of the Heroes of the Storm championship altogether.
"We'll continue actively supporting the game with new heroes, themed events, and other content that our community loves, though the cadence will change," writes Blizzard in the news blog. This isn't necessarily a cancellation of Heroes of the Storm however as Blizzard notes it is setting the MOBA up for "Long-term sustainability."
The language belies the current state of Heroes of the Storm which has not been as popular as Blizzard's other esports games. Compare the total viewership for the HGC Grand Finals 2018 which counted about 3 million total views on Twitch according to ESC Watch. Compare that to Hearthstone's World Championships which totaled 10 million views on Twitch.
So, while Heroes of the Storm will likely see new content in the form of heroes, Blizzard appears to be phasing out the esports arm of the game in favor of its other esports like Overwatch while also moving developers into projects with higher priority.
