Now that the NDA has been lifted, it's possible for the public to view what kind of discussions go on between the testers and the developers. I could dig up some older post from the alpha forums, but it would probably just confuse everyone as a lot of things have now been changed.
This is simply sort of an FYI for the current state of frost, at least in my opinion.
Here is the post.
Edit: And this is why I love alpha/beta forums so, so much more. The devs not only actively read intelligent posts, but they also take the time to respond to them as well. In fact, by the end of the alpha, I believe at least 30% of the threads on the DK forums had at least one blue post in them.
