First off, I wanted to acknowledge the time you've obviously putting your thoughts together in a constructive way. It's very appreciated.
Second off, I am not going to address each concern individually for you here because there is only so much I can say or remark on. I can say though that we've been keeping a close eye on the continued feedback we've been seeing, reading, and hearing from the community and we're not blind to concerns. As always though, we have to keep perspective in mind as to what people are actually doing in game versus what they are saying online (in a variety of venues) and try to balance it all out with what we feel makes the most sense for the longevity and health of the game.
We're holding back a little on Mists of Pandaria (new at least) information until the press event we're holding in March, but hopefully you'll like what you hear and see that there has been progress in trying to address some concerns we see and hear on a regular basis.
We also have some additional items we're preparing to put out to the public that explains a bit more about the thought processes that went into Cataclysm, what we think went well and liked, and what we think could have been done better as a set up prior to the press event. Hopefully it will shed a bit more light on things.
While we'd love to acknowledge every bit of good feedback we see, but it's just not practical. We do try to acknowledge what we can though when we can and have in the past.
That all said, as always, ongoing discussing and constructive feedback is always welcome and appreciated.
