Fireside Chat Developer Panel Recap - News - Hearthstone
Breakdown of their panel. No new dust, same crafting costs.
The very first subject is randomness where Ben Brode makes the case for increasing the randomness in HS. Basically, adding more randomness increases the amount of player skill needed to perform well. Also, it increases the frequency of awesome things happening (Rag hitting the right target, getting a good Brawl, etc).
I'll drink the kool aid for now, and we'll see how it actually plays out next month.
edit: Also, there's more cards on that link. Ex Spare Parts are random 1 mana cards that can swap hp/atk, give +1 hp, +1 atk. Then there's a new Warrior card, Bouncing Blade: 3 mana, deal 1 damage to a random minion, repeat until a minion dies.
