However, doing serious testing you have to know what you have to test at all.
We're not serious testers.
Sure, no one is obligated to help or not, but like I said, strategically it would have been better to attract more players to test it.
I'm pretty sure testing everything was only part of the reason they did this, as they have their own QA team and their own procedures for noticing and fixing bugs. Not that us reporting bugs isn't useful, but I imagine they already know about most of the bugs in the game right now, and would be more interested in what the community feels are unacceptable bugs
The main thing they're looking for, as we've seen in most of their posts talking about the beta, is feedback and how well we personally think the systems work. I'm not saying that as a guess, either, just look at what they stated.
"By launching our first Open Beta, of course! In this way you will have a chance to experience all the juicy parts of Update 1.2, but also share your feedback with us in advance, allowing us to improve what we are currently working on." -Dev Diary 73
"Your feedback, ideas, and discussions have all been instrumental in helping the team prioritize our time and efforts for this update." -Dev diary 74.
I'm not sure why I can't quote them, but anyways, they're clearly looking for our opinions about the features. A changelog isn't necessary, they want to know more about how we feel about the new mechanics and if there's anything they can add or tweak to make it more fun or intuitive.
