That front cover/promotional image references Warcraft cosmology, therefore the product is objectively bad and should be consigned to oblivion.
In all seriousness though, just looks like something pretty for collectors and enthusiasts. I’d be surprised if they hide any lore in a tarot guidebook.
Best Wowhead comment: “Next up, healing crystals and salt lamps.”
While I disregard the idea of using tarot decks to divine any sort of accurate information, I think there’s value in the archetypes of the major arcana.
They perform the same function as tropes. If a character is associated with the High Priestess or the Chariot, that provides me about as much information as someone calling that character a Team Mom or Go-Getter.
For that reason, I’m mildly interested in learning what character they will associate with each of the major arcana, since that will tell us what the person in charge of the project thinks about those characters, but otherwise, I don’t really care about it.
I mean weren’t Tarot card decks a Legion Acheaology grey item, because Highborne were fiercely superstitious?
Perhaps this is an tradition that went on to become widespread across Azeroth, like with how Highborne made the Wizard Hat a major thing for Magi?
Anyone mentioned the Lor’themar and Thalyssra island hopping, honeymoon adventure book yet? 
Unfortunately it’s an Exploring book.
And Blizzard’s track record with those is, respectfully, [REDACTED]

amazon listing for the curious.
Betwixt the sweeping seas of Azeroth, islands and isles await, bursting with splendid treasures—powerful artifacts, enchanted armor, and rousing tales from ages past. With duty delaying their honeymoon for years, First Arcanist Thalyssra and Lord Regent Lor’themar Theron finally resolve to set sail, seeking the perfect setting to celebrate their love. Join the happy couple as they travel to distant shores, scouting for the perfect sunset and learning that it is the journey—and those with whom we share it—that should be cherished most. From the magnificent Suramar and the lush jungles of Zandalar to the rugged seas of Kul Tiras and the verdant beaches of the Dragon Isles, Exploring Azeroth: Islands & Isles is your next step in a charming voyage across Azeroth.
Hopefully it’ll be the first Exploring Azeroth book that doesn’t just describe what exists in-game through the lens of the author(s), but don’t hold your breath.
Don’t be surprised if it describes how the Gilneans and Forsaken are still fighting over warden towers, or something equally inane.
Non-0% chance Lor’themar will apologise for the Purge now whilst taking a romantic stroll through Boralus with his sun-bending Dusk Lilly.
Aslong as Thalyssra doesn’t dare step into Bel’ameth after she hopped onto the Night Elf genociding Horde-wagon because Tyrande did not drop to her knees to beg her back into Kaldorei-society after Legion. 
Huh, they just lumped all the isles together? Can’t wait to read how demons are still attacking Azsuna, half of Val’sharah is still Nightmare-corrupted, and the damage to Dalaran’s walls wasn’t repaired because the breaches turned into tourist landmarks.
Also like to read how the Blood Trolls are still in Zuldazar (Dazar’alor?) and a proper problem in Nazmir!
Or how the Alliance Purge Squads are still purging the Vulpera in Vol’dun(wish that is still happening for real, though😏)
“I feel like if I get this, I’m going to see one card-character assignment that I don’t agree with and try to eat the deck in rage.”
This will be me if I get the tarot deck.
Watch them use the jailer for death.
Well use of the Jailer did kill a lot of people’s interest…
It just fits.
The death card is usually associated with a new beginning–
Oh…
Tarot cards never invoked anything in me. Its the same kind of stuff as horoscopes.
If your fate can decided by mundane things like drawing a card or which constellation you were born under, what’s the point of struggling against fate? If the game’s rigged, the only right move is not to play.
Draenei themed of course.
Counterpoint just to be that way: if it isn’t the constellations, then it’s the social station of your parents, which you’re statistically unlikely to break out of. You’re also facing human-built structures of interaction and rules which force compliance without consent, and to top it all off, you’re not a billionaire. Free will is an illusion.
What say you?
Well thats the point isn’t it? It’s one thing to believe in shackles of society, upbringinging and/or cultural norms, which are all very real, and another thing to subscribe to a literal dice in the form of constellations or a card tobdecide your fate.
If you believe in those, then you are well and truly without the ability to exercise your free will in practise. It feels like you kind of give up at the start of the game.
The power move is to not let any shackles you do not want weighing you down weigh you down. Complete freedom is not ideal either.
How different would you describe the end results of these two things?
one’s a cosmically ordained destiny, the others man-made/a social construct - it’s a “divinely ordained” sort of thing where some are inherently the ones deserving of rule and power over others, and the others are inherently servile creatures that must obey, and opposing this would be opposing natural laws (rather than unfair elements within a society)
Tarot cards are cool solely because there’s usually cool art on them, so this is a neat product!
