Hearthstone’s quests are about to change. With the start of the upcoming Year of the Raven, the rewards you get for playing Blizzard’s CCG are about to get a lot more generous.
For one thing, the amount of gold you receive for completing quests is set to go up. Most quests won’t change, but 40 gold quests will now all be worth 50 gold. That means that once you’ve completed two quests - no matter what they are - you’ll always be able to buy a new card pack.
