Blizzard gets more and more communicative every week recently. I love it. They recently announced that they're seeking questions for a community question and answer series, with a separate thread for each class. They'll be going through the class threads in order, answering questions and generally being awesome (one hopes). Afterwards everything will be gathered into one big blue pile of answers and presented to the community.
Nethaera is going to be the organizer of this little event, it seems. She warns us that it is "probably going to be a couple of weeks" before we start getting answers, because they want to give sufficient time for WoW players around the world to get their questions in. She also says she's going to try to get "the most prominent questions" answered, as well as questions that have been around for a long time without being addressed.
This is a great time to get your class questions and concerns addressed, so if you have anything you've always wanted to ask a dev, go find the Q&A thread for your class (in your class forum) and post away.
