How do you arrive at specific changes when balancing classes?
Statistics from the playerbase ranging from what cards you have in your deck, to win / loss ratios.
Blizzard's internal high-level playerbase often provides insight into how things can change at the top end of play.
Checking on what the community has to say about specific cards and matchups.
Why are you not interested in doing chat against random opponents?
We want to keep the game accessible to everyone. No one enjoys being harassed by their opponent.
Keeping chat to emotes keeps the game flowing at a quicker pace. No one is stopping to type.
How are you planning on improving the social experience?
We've got some ideas, but nothing is concrete. More information in the months to come.
Toasts were recently added to the game which has increased the social aspect of Hearthstone a little bit.
How does the ranked matchmaking system work?
It is based on an internal rating, and to a lesser extent, how many games you've played.
Having games played counting towards your rank helps people not move through the system too quickly.
The developers are currently not satisfied with the current ranking system, and are working on changes.
We will very likely see changes to the ranking system before the game goes live.
What do you think the community wants the most right now?
Players really want a spectator mode!
Lots of interest and desire from players to watch competitive games.
We're looking to build that into our development roadmap into the months to come.
The Arena. Are you considering adding a free version?
There are definitely ways it could happen, but they don't want to the Arena to lose its focus.
Redesigning the Arena is out of scope during the beta.
