The new game mode “Arena” for Heroes of the Storm has been postponed. The feedback at BlizzCon is the reason for this.
A Winter Without Arena
It was proudly presented at BlizzCon, the new game mode “Arena”, which fans should be able to experience in the live version of the game in the “near future”. However, good things take time and Blizzard took the feedback from the event attendees to heart, leading to the postponement of the Arena mode.

Unlike the regular game mode, the Arena is about short, brutal battles. Especially newcomers should feel comfortable here, as it is not necessary to gather experience points or select talents – only the heroic ability can be determined.
In response to a fan’s question about whether the Arena mode would still be released in the first quarter of 2016, they apologized and confirmed that it would take “longer”. There was no exact date or even an estimate provided.
