It ' s OP ' s mom . She ' s used to taking it in . <| sep |> Naxx was amazing though . Don ' t get me wrong LoE which in my opinion is the only real contender was an awesome set for hs , and improved the quality of the competitive game as a whole a ton . If it was based purely off which set improved hearthstone the most my vote would be for LoE too . But Naxx was special . It was the first expansion , so it had a lot to live up to , especially with the weight of the raid its name was from . And man did it deliver , so many powerful cards , that it just completely turned the game sideways . Admittedly aggro got too much , but control got sweet tools like deathlord and belcher for stemming the tide effectively , and loatheb was cool for all types of decks , helping prevent otk against combo or prevent control from stabilizing as aggro . Almost every single class got multiple notable cards from it , even with only 1 class card per class . It just changed the game so much , for better or for worse , and it was awesome to see . Plus , the adventure itself was loads of fun and you gotta love KT .
