Q: I play World of Warcraft, too! Can I earn anything for my WoW characters by playing Hearthstone?
A: We’re looking into a few possibilities and hope to have more details to share in the future.
Looking into it? I would bet that they will have details very soon and Wow loot will drop.. As others have said it would be a huge opportunity missed and most would welcome it.
Yeah first thing I thought of. Also... WTB collector's edition Hearthstone with special pets/SC portraits/D3 vanity items... and there should be some kind of vanity system within Hearthstone so the other Blizzard CEs give you something shiny. Card reskins maybe?
Are there achievements in Hearthstone?
Nope. I asked it is a stand alone product that is not meant to enhance your game play in their other games. Its a game your gonna play because its fun, not to have x% of getting a new wow mount or diablo item.
