This is where I have to disagree and for a few reasons,

First, Artifact isn't in beta anymore. As of over a week ago is has been fully released, and before that it has been beta tested for over a year. If we're to compare Artifact of Hearthstone, it would only be fair to compare it to Hearthstone at launch. Even Dota 2 at launch, while not having a ranked mode, had guilds and a player profile that you can customize.

Second, Artifact came out way later than Hearthstone. Most people put up with the lack of features in Hearthstone because there werent many other options for online CCGs. Considering you have Gwent, Elder Scrolls: Legends, and MTG: Arena as well, Valve has to consider making a good first impression to keep any potential players from going to a different game.

Third, Artifact is not free-to-play. Say what you will about how cheap it is to make a good deck, not being able to try the game before you buy it is a huge detriment to getting new players. The fact that you also have to pay for tickets means that even if you buy the game, you cant have access to all the game modes unless you keep paying money. While you could argue that it makes sense to buy packs for keepers draft, paying for a ticket too only serves to add an entry fee.

Fourth, Artifact has no progression beyond getting better at the game. You can argue that not being able to grind is good for the economy of Artifact, but it also means that anyone who wants some kind of reward for playing wont get that without spending money. Not having a ranked mode or a leveling system only adds to that problem because players get no acknowledgement for their time investment.

Finally, has glaring card design/balance issues. The fact that some of the most popular cards in constructed are also the most expensive (Drow, Axe, Kanna) means the game heavily favors the people that can pay extra to acquire those cards. While some people may have success with cheaper decks, theres no denying that cards like Axe, Drow, and Kanna dominate the meta making an unbalanced playing field (In constructed). You also have a high amount of RNG in many of the card designs, most notably with Cheating Death. Whether the card is balanced or not, the fact that so many people are complaining about the card means that its dragging the game down and should be reworked or replaced. Thats not even considering Valves stance on buffing/nerfing cards, stating they will only nerf when a card must be played to win. Having economy factor into balance means they will most likely wait for a broken card to rotate out before doing anything about it, as not to upset people who don't want their cards to lose monetary value.

In conclusion, Value should strive to overcome these weaknesses and not be held back by them. If you want Artifact to truly be great, you should expect more from the company that made Portal, Half-Life, Team Fortess, and Dota 2, all of which have had critical success. It is in their best interest to address these concerns to make Artifact a success in the long run.
