An excellent addition to the Hearthstone single-player Adventures, featuring true-to-raid encounters that make clever use of game mechanics and introduce new dragon-centric cards
While it may not look as dazzling as Naxxramas, Blackrock Mountain expansion is still the best add-on yet, edging out the card-only Goblins vs Gnomes. I'm still chipping away at the Heroic fights, and with how many card options are available at this point, I'll probably be messing around with custom decks for weeks.
We may have to wait for the revolution, but Blackrock Mountain is business as usual for Hearthstone. And business is good.
Of course, the benefit with Adventures is that you know exactly what cards you'll unlock, so it's still a good investment if you know the cards are right for you. But even if we think the spoils aren't quite as good as last time, 'Blackrock Mountain' is an Adventure that in many ways hits harder than 'Curse of Naxxramas' did. If it's more surprising, rule-breaking encounters that you're after, then look no further.
What Blackrock Mountain brings to Hearthstone is a memorable experience, but not much in terms of actual card value. Many of the cards obtained in the adventure are incredibly situational and most likely aren't going to see much play. There was, however, a lot of thought and effort put into designing the boss encounters, and it also allows for some interesting deck constructions in the arena mode.
As a single-player campaign, Blackrock Mountain isn't quite as well-tuned as Curse of Naxxramas, but it makes up for that shortcoming by somehow being even funnier. It proves that Naxx wasn't a fluke – these adventures aren't just convoluted card-delivery systems, they're legitimately fun experiences in their own right.
