Ofc I tried almost everything in the first evening when I encountered this problem. I also wrote a letter to the Technical Support and received the answer: “It is a known issue and our developers already investigating it.
You can track updates with the following link https://us.forums.blizzard.com/en/hearthstone/t/330-known-issues/148159 or submit a new bug report here https://eu.forums.blizzard.com/en/hearthstone/c/technical-support/6/”.
So it is a known issue. And I do believe they are really working on it.
But there are some issues that are more about relationships with the community than about technical support. The technical support is not responsible for it.
This bug happens during the brawl that was a source of getting packs for strong ftp players. I personally counted on this brawl when making my in-game economic decisions.
(And also I don’t think they lose too much by having ~ a thousand people getting 4 packs instead of 3 packs for 300 gold. Lower ranks usually can’t get 6 wins in the brawl many times.)
They also didn’t give any warnings like “Sorry, the brawl might not be available, so don’t waste all your dust on smth like crafting your homebrew deck with 10 legendaries that, you think, should be an ideal counter deck for that annoying top-100 wild Hostage Mage. And crafting it in gold after you finally won is also not a good idea”. Well, I personally haven’t made such extravagant decisions, but…
I was still relatively careless. Skills were always equal to getting resources in this game. You get more rewards if you reach D5, legend etc. You could play brawls and win. It’s not very fair to form such a habit, and then – oh, sorry, we have a bug.
