There’s nothing wrong with playing by yourself, you lonely soul you. There must be quite a few like minds, because Hearthstone continues to pour resources into its solo modes, such as the new Rumble Run that came with the Rastakhan’s Rumble expansion.
Rumble Run got a tune-up on Thursday now that Blizzard’s had some time to evaluate and plan the future of the feature. The update nerfed boss decks a little to make them feel more fair, weighted card rewards, and keeps shrines constant when players lose a boss fight.
Blizzard also said that it tweaked the arena: “Following our Arena update last December, we have adjusted the appearance rate of each individual card available in Arena to ensure the overall win-rate of each class remains as close as possible to our ideal of 50%.”
