Could someone tell me if Hearthsone became pay to win or not?
I don't precisely think so, so sort of no. Nowadays there are more cards you might want to include in your deck and that comes with having a larger global pool of cards. Some of the new cards do synergise slightly better with some older deck themes, so chances are if you had a deck that has been going since, say, official release, you'd want to swap some cards. However, that's not strictly necessary a lot of the time.
The adventure expansions, in particular, add some relatively solid card for relatively low cost. Well, "low cost" since they can be deterministically obtained, a opposed to the RNG factor that the card packs are. The gold isn't really that much - I've got both of them through just playing the game. So, more or less, I'd say that you could start playing the game and save up for the adventures to get some cards - Naxxramas, in my opinion, had some better cards, or at least they appeal more to my playstyle. Blackrock Mountain was more dragon themed which I tried but found meh.
Overall, I'd say that you can win without paying. Yeah, you'd need to put some playtime instead but as a F2P game, and furthermore, a Blizzard game, I guess that's normally to be expected.
However, I do want something to be noted - I don't think Heathstone is
entirely veering away from being the so called "pay to win". With the expansion of the card pool, you generally have a harder time gathering the cards you need/want for a deck. That's concerning new players, here - when I started up, it was right at the start of the open beta[footnote]actually, slightly amusing story here - I got an invite for the closed beta. And that was on a Friday, the open beta came the following Monday.[/footnote] and I've been playing on and off since then on a relatively steady pace - I'd occasionally skip a month or something but would otherwise log and clear most quests. So, overall steady but not overwhelming play for which I got cards. When each of the expansions came, it the cards weren't mandatory but nice addition and my old decks still worked, so steady play slowly started to get me new cards. That's with each expansion. However, a new player would have a hard time starting up and the gulf between somebody like me, who has build up some cards, and a newcomer with none is going to be very large. The situation is going to get even worse with each expansion that comes out. So, sure, technically paying for card packs is not mandatory but it does leave people at a disadvantage - they
could put some playtime in instead but as the list of available cards grows, they'd need more and more just to get on some stable footing. And yes, cheap decks and relatively effective decks exist but they are still just means to grind in order to get the cards you need for something else.
In summary, again - Hearthstone is not exactly "pay to win" but not exactly a game you just pick up and play on a whim and for absolutely free.
