The main problem is the power creep and it will never get better, as they have to make more and more OP cards to sell their s****. It was always worse and worse after every expansion but you don't even need to think very hard, just look at how they created Demon Hunter - 0 brain, OP cards and even after 4 or 5 nerfs, he still had one of the best decks in Standard.

The second problem is that they're inconsistent - they nerfed Innervate for example a few months ago, saying the mana cheat is too much, but now we get cards like Bloom. They said there'll be free adventures only and they won't lock cards behind a paywall - just another lie. It's all about money, they want you to spend on packs and cards as much as possible. Would be ok with a fair system but it's far from it.

That's why they give new cards to streamers to try out. Back then, a few years ago it was good to wait for new content as people usually experimented with it in the first 1-2 days at least. Now it's totally different, we have the most OP combos for day 1, all you have to do is to buy the packs/craft them. They totally killed the hype and regardless of the new cards, you feel like the meta is already boring as you see the same decks over and over again.
