More details will be available in upcoming blogs on the official Hearthstone and World of Warcraft sites.
Edit: It will need to be done on the same Battle.net account that your Hearthstone account is on, though. World of Warcraft Starter Edition is free, so that should help even if your existing accounts are separate.

About Liadrin

In World of Warcraft, Lady Liadrin is the leader of the Blood Knights. She wears Tier 3 Redemption Armor and  Blood Knight Tabard, and wields  Quel'Delar, Might of the Faithful.

At the start of Burning Crusade, this order drew their powers from the subdued naaru M’uru. When M’uru was stolen from Silvermoon, Lady Liadrin went to A’dal in Shattrath City to find a new source of power. Below is her conversation with A’dal:



Liadrin then joined the Shattered Sun Offensive and joined Prophet Velen after the defeat of Kil'jaeden when the Sunwell is purified.
Prophet Velen says: Mortal heroes, your victory here today was foretold long ago. My brother's anguished cry of defeat will echo across the universe, bringing renewed hope to all those who still stand against the Burning Crusade.
Prophet Velen says: As the Legion's final defeat draws ever-nearer, stand proud in the knowledge that you have saved worlds without number from the flame. Just as this day marks an ending, so too does it herald a new beginning...
Prophet Velen summons a large crystal from the sky. The crystal hovers above the Sunwell.
Prophet Velen says: The creature Entropius, whom you were forced to destroy, was once the noble naaru, M'uru. In life, M'uru channeled vast energies of LIGHT and HOPE. For a time, a misguided few sought to steal those energies...
Lady Liadrin says: Our arrogance was unpardonable. We damned one of the most noble beings of all. We may never atone for this sin.
Prophet Velen says: Then fortunate it is, that I have reclaimed the noble naaru's spark from where it fell! Where faith dwells, hope is never lost, young blood elf.
Lady Liadrin says: Can it be?
Prophet Velen says: Gaze now, mortals - upon the HEART OF M'URU! Unblemished. Bathed by the light of Creation - just as it was at the Dawn.
The heart of M'uru disintegrates and flows into the Sunwell. The Sunwell reignites in a fount of blinding light.
Prophet Velen says: In time, the light and hope held within - will rebirth more than this mere fount of power... Mayhap, they will rebirth the soul of a nation.
Lady Liadrin says: Blessed ancestors! I feel it... so much love... so much grace... there are... no words... impossible to describe...
Prophet Velen says: Salvation, young one. It waits for us all.
Prophet Velen says: Farewell…
Lady Liadrin is once again found in the Sunwell in Wrath as part of the The Sword in the Skull questline.

Lady Liadrin:
"My brothers and sisters, words cannot describe what I felt upon seeing the Sunwell rekindled."
"In that moment, the Light revealed to me the truth of the terrible things I had done."
"Our people had walked a dark path and mine was among the darkest of them all."
"But the Light showed me that I was not lost. It helped me to find the strength to survive in spite of all that had happened and all the evil I had wrought."
"It is a strength that we sin'dorei all share. It is a strength we will need to free ourselves of the addiction ravaging our people."
"It will be the most difficult battle we have ever faced, but our resolve and the power of the Sunwell will sustain us until we have been restored to our greatness."

Blood Elf Pilgrim:
"Well said, my lady. We sin'dorei will be free and we shall be great again!”
In Warlords of Draenor, Liadrin is fighting at the Dark Portal and for the Horde in Talador. There is also a Garrison Ship named after her.

Tier 9 Horde armor is called Liadrin's Battlegear and one of the top rewards from Trial of the Grand Crusader was  Lady Liadrin's Conviction.

In Legion, Liadrin is found in the Paladin Order Hall and is an Order Hall Champion.

Once you make your changes and click back, you'll be brought right back to the deck selection page. No more accidentally queuing into a ranked game!

New Tavern Brawls

One of these is obviously a Kel'Thuzad versus Rafaam brawl. KT starts with 30 health and has Necromancy and Mr. Bigglesworth himself! Rafaam on the other hand begins at 60 health and Staff, First Piece. The best thing about Rafaam? It looks like his hero power can be upgraded as the match goes on: Staff, First Piece, Staff, Two Pieces, Staff of Origination.

Another features the City of Stormwind as a hero with the special Barracks hero power.

Faction War has Annoy-o-Tron Prime with Hello! Hello! Hello! and some associated cards along with Nefarian with his standard Wild Magic hero power.

For a look at specific Tavern Brawl cards, head to the bottom of the post.

Deck Slots And You!

Originally posted by Blizzard (View Original)Collapse

The Innkeeper has worked some magic to extend nine additional deck slots to Hearthstone players everywhere with patch 4.2! Experienced players will find 9 “new” Basic decks in their deck lists that can be edited, deleted, or renamed, while newer players can now edit their Basic decks before unlocking the extra slots.

So Much Room for Activities
Everyone will have access to the new deck slots, but some players will need to unlock them first. Fortunately, that’ll be simple: once you unlock all nine Hearthstone Heroes by defeating them in Solo Adventures Practice mode, you’ll also unlock nine additional deck slots, bringing your total number to eighteen!

Veteran Players

If you’re an experienced player, your new deck slots are likely unlocked already. Open your Collection Manager and scroll down to reveal your additional deck slots. You can scroll through all of your deck slots by using the slider on the right.

You’ll find nine new Basic decks—one for each Class. You can edit, delete, or re-name them, just as you can with any other deck slot.

New Players
Deck slots will work differently for new players. Rather than starting with nine slots, new players will unlock a Basic class slot for each Hero they’ve unlocked. Those Basic decks can be edited, but each one is dedicated to a specific hero. After all nine Hearthstone Heroes are unlocked, you’ll receive nine extra deck slots, and you’ll also be able to delete and replace the original nine Basic decks.

Ready for Action!
Choosing a deck to play in a match should be very familiar, but now you’ll have an extra page in the Deck Selection screen if you’ve created more than nine decks. You’ll see a gold arrow to the right or left of your deck page—select the arrow to switch which deck page is displayed, then choose the deck you want to use for your match.

These deck slots will work just like they always have: you can use them for Casual and Ranked play, Friendly Challenges, and Adventures.

That’s everything, so head to the Collection Manager to start experimenting with your new deck slots!
