On data collection site HSReplay, which uses the Hearthstone Deck Tracker app to gather class win rates and more, Demon Hunters are well ahead of the second-most successful classes, Rogue and Hunter. Though they only have a handful of cards compared to the other classes in Hearthstone-Priests, Rogues, and the like have a full year worth of expansion cards behind them, Demon Hunters have not-Illidan and his fel friends lead the pack early on. However, it seems like not everyone was prepared for the impact Hearthstone's newly added class would have: Demon Hunters are dominating the meta. With three expansions rotating out as the Year of the Phoenix arrived, change was bound to happen. Hearthstone's Ashes of Outland expansion launched yesterday, and it has made big waves to the game.
