One thing I was wondering about earlier: Do you think it's better to do a slow release of cards like they're doing with Naxx or just dump a batch of new cards in all at once? Or, ultimately, doesn't it matter?
Right now it seems that people are taking old deck concepts (Zoo, Hunter, Control Warrior) and adapting them to the new cards as they get released. If all of the cards were dumped out all at once, I have a feeling that we'd see a lot more brand new decks instead of just updates to old ones. But, also, I'm not sure that it matters either because in a month, I think the landscape will look completely different. It just seems that right now, people are more focused on tweaking what has worked before instead of trying for new things.
