What are we talking in terms of comparable? Similar business model? Probably. They're often more generous because they have to be. In terms of actual scale or size? Nothing is really on par with Hearthstone.
My math was a little off, but from Gadgetzan to the latest set you should have enough for at the bare minimum 48 packs if you were doing your dailies, more likely somewhere 60+ when you add in gold for winning three and dailies worth more than 40. Plus you'll be getting dust back from Azure Drakes which every player should have, and anyone who's been playing for a while will be getting Ragnaros and Sylvanas dust too. Bonus packs and dust from monthly rewards too, and it's easy enough to hit a decent rank cheaply with pirates.
That's the horrible part of Hearthstone's business model--60 packs isn't that great. I remember people posting the epics and legendaries they'd get for their $50 for 50 packs Old Gods pre-purchases, and they'd end up with a scant few of each. How many other games can get away with such a bad value for money? It baffles me. $50 will get you an embarrassingly huge amount of top-quality content in virtually any other genre. I can get an insanely detailed grand strategy game, or an RPG on the scale of the Witcher 3, or even invest in a physical card game like Netrunner and pay for known, pre-defined card sets.
I'd also say that the business model makes situations like the pirate-dominated meta vastly more common. Players can't just craft cards to toy around with--if they do, they'll spend a crazy amount of money to keep up. They can either resign themselves to not being competitive or just stick with popular decks. Whale-focused F2P kills experimentation and deckbuilding creativity.
It won't be as nice as it was with this price increase and adventures being dropped, but I think I've only ever spent money on packs twice over two years, and once was the little intro pack promotion they did.
I played since beta and never once spent money on the game. Had Blizzard gone with an adventure-only model (ie. you spend a set amount of money and get set cards), I would have started buying those, and would have been a regular, steady source of revenue for maybe years.
Instead, their whale-focused model meant I gradually switched to just watching Youtube Kripp/Kibler/Strifecro highlights, and then nothing (except bitterly posting in Hearthstone threads, haha).
I mean I'm probably done with the game pretty soon, but that's less to do with the business model and more that I just keep forgetting to play it because my time is taken up with other games and things to do.
I wish I didn't have to be done with the game. It's so well-designed in so many ways.
