Players! Justice is served!
Quote from Blizzard
Hello everyone,
Yesterday, we disabled Heroic Duels to prevent malicious users from using third party software to break deckbuilding restrictions. This is a violation of our Terms of Service, and the offending accounts have been banned.
We are currently testing a fix to close the vulnerability as soon as possible. Once confirmed, this will be added in a server-side hotfix and the Heroic Duels queue will be reenabled.
Additionally, players who had lost Heroic Duels games to illegal decks will receive 10 Tavern Tickets–these will be granted to impacted player accounts next week.
Thank you for your patience.
My thoughts : Not looking forward to Duels getting removed in april. I love playing duels. I play it way more than Arena/Mercenaries etc.
