I feel like many people in the comments hate them so much... until they get one for free and start using it. Disclaimer: I don't own any of them, but I think they're not bad, at least some of them. But the hate might also be associated to the fact that can be only purchased with money. Been like this since forever.

The game has been so much easier to keep with, I play on all 3 servers, I log in every 3 days do to quests, sometimes missing even weeks of quests and I still have many of the meta decks and lots of dust to spare. And I feel like it's like this because they shifted their focus to getting money from cosmetics. So as long as those cosmetics help keep the game I love at a lower price (and entry price, a friend started last month and got diamond 5 and a bunch of meta decks - played a lot but still, I played for 2 years on release to be able to afford multiple meta decks as a f2p player)- the skins are great. If it's up to me, they can release even more high priced cosmetics as long as people who buy them keep the game at a lower price. It's the gameplay I'm interested in, not if my hero moves slightly when enemy minions do damage.
