Shoot away.
I just want to say that questions about class changes or balance, gameplay mechanics and such is not that exciting as these things come out eventually in a Blizzard blog.
What is exciting is to get game developers like Chris Metzen to start talking personally about what he thinks about these heroes you like, or villains.. get him start talking about some lore, pluck his brain!
Same goes for other developers, ask questions that we would like to know something about.. something that goes on in the background that they do not talk about if not asked about it, you know.. less of the yes\no\maybe ~ questions.
PS: Questions about, "Will we get Gnome Hunter soon?" "Can we have a legendary shield soon?" are yes \ no or joke answers from the developers, not very interesting, to be honest, in my opinion tho.
