In Hearthstone there should definitely be more deck slots. To my knowledge it's planned, but you'd think it wouldn't be too difficult or take this much time.
Also it'd be great if alternative heroes were able to be bought with gold. I don't care how much, I'd be glad to save up 2,000 gold for Medivh or Alleria. Also, regardless of whether or not they are purchasable with gold (although I don't see it happening), I do hope they release more heroes soon. It's been a while and they have yet to announce alternative heroes for any of the other classes.
