Honestly, on one hand it sucks that the reception of the newest update was such a downer on you guys.
On the other hand, I can understand the pain of the people - since the beginning, every single time you guys made a big update, the result was a lot of great, high quality content.
Not only that, but I noticed that there was a miscommunication issue here - even though you guys have said that this update was about 'polishing the episode one', nobody knew what that entails and how much of a new content there will be.
So if we combine these two things with the fact that people had waited a LONG time, I think it is understandable that some people are pewed.
In a way, you guys had dug your own graves - you've set the expectation of the people so high that only a LARGE content update would fully satisfy the naysayers. (I am not attacking you here, it's just how I see it.)
Honestly, the only thing that I think about that would prevent another 'blowout' like that in the future, would be to be much more transparent with the amount of new content new updates bring. If people knew how little new content the last update brought in advance, then the amount of the displeasure would've been much lower.
I hope that the communication issues with the fanbase will be resolved in the future and new update will be celebrated by the all.
