Come on guys. That's not the way to go about it. It's not like you figured out at the last moment that there could be a delay. You should have told people earlier. Surprise moves are never good in this industry, I thought you have learned that after midwinter update. You opened a PTR server seemingly to test new features and card interactions and just after that you hit everyone with the midwinter update. People had their decks pretty much tuned, we had a stable meta, everything was going smoothly. People were happy and pumped. PTR server could have revealed all the bugs and gave you time to fix them, no drama. But no. You decided to push the update without any heads-up, pushing holiday bags of kegs with seemingly lowered drop rates and releasing a game full of bugs and balance issues. Mid season.
My humble suggestion: give people a week's notice before every patch, every new feature, every delay, every event, etc. People will appreciate that. I know I will.
Was this move necessary? I don't think so. We all know that meta isn't balanced. We all know the game is full of bugs. People are sick of it. It took a while to get a response from the developers, but it's not the kind of response people wanted. I think the season should have ended as scheduled and if you needed a bit more time to release a patch, then you should have pushed the start of a new season to 11th, allowing three days without the ranked ladder. I think it wouldn't cause as many complains.
The toughest job ahead of you now is regaining the trust of the community. Please, hire some people to help Burza and listen, actually listen to what people say. And let them know that you listen. Nobody in the community wanted this meta to last two days longer, nobody expected it, there was a fundamental lack of communication between you, the developers, and us, the players. There were tons of suggestions in the forums and rarely any reply from your representatives. I'm one of the players that used to support you, even though I had some gripes with the game, I was buying kegs and tried to post my suggestions, but I have no more incentive for it. Did somebody read them? I have no way of knowing, because no one from your team is replying. Sometimes it feels like talking to the wall. Please, learn from this. Good luck.
