One of Hearthstone's largest ongoing team leagues, Hearthstone Team Story, has been put on hold temporarily, allegedly due to its gambling aspects in its fourth season.
The format for this season of Team Story included some form of simulated gambling, where a dealer seemingly would "bet" on matches with chips. The footage linked doesn't make it clear if the players were the ones betting or if it was the dealer betting against the players.
This isn't the first time that poker-like elements have made their way into Hearthstone. The World Series of Sealed event combined elements of poker and betting, and was even seemingly endorsed by Blizzard:
It's possible that Blizzard US themselves had no issue with the event, and it was instead halted by Blizzard China. Blizzard China is operated independently of Blizzard in the west and has different rules that they make esports events abide by.
We've reached out to Blizzard for comment on the temporary halting of the Hearthstone event and will update if we hear back.
