Battlegrounds Ratings Update
External Battlegrounds ratings will be reset for all players and a new progression system will be introduced. The new system is similar to the progression system players are familiar with from our constructed Ranked mode.
Players will see their rating reset to 0, and all new players will start with 0 rating. With every Top 4 placement, players will gain rating—up to 300 per win. A player’s rating will never go below 0, and they cannot lose rating until they’ve climbed above 2000.
Here are the nuts and bolts of how the new system works:
- Between 2000 and 6000 rating, every 500 rating (2500, 3000, etc.) will act as a new rating floor where you cannot lose rating.
- Below 6500 rating, players will earn a small bonus to their rating gains at the end of each match, which will in turn make for a faster climb.
- Rating losses will remain consistent.
Matchmaking will now be done based on the player’s invisible internal rating, which we’ve been tracking since Battlegrounds launched. Internal ratings for players will not be reset and will not be affected by the above modifications to external ratings. When your external rating is lower than your internal rating, you will gain rating faster. Read more about the ratings update in our Dev Insights blog!
Please note that your rating will not visibly reset until you’ve played at least one Battlegrounds game!

Tortollan Pilgrim and Guardian Animals will be eligible for a full dust refund for 2 weeks after the 18.4 patch goes live.
Bug Fixes & Game Improvements
- Fixed a Battlegrounds bug where Micro Mummy would cause a crash when tripled. Micro Mummy has returned to the Battlegrounds minion pool.

- Galakrond will no longer lose its partially invoked status when being shuffled back into your deck from hand.
- The mana reduction from Nature Studies is now cleared if the spell is countered.
- Golden Sightless Watcher’s history tile now correctly shows the gold/non-gold status of the discover options, rather than forcing them to all be gold.

We’re giving all players one free Arena ticket to celebrate the return of Dual-Class Arena! When you start an Arena run during the Masquerade Ball event, you’ll choose a Hero before choosing a Hero Power from a different class. Card offerings will feature cards from BOTH classes, in addition to neutral cards!

Complete a Secret Quest
After a thorough examination of garments in our lost and found cupboard, Transfer Student has embarked on a laborious journey to find the perfect costume for the Masquerade Ball! We’ve identified an itinerary in the dormitory that outlines an intention to visit Dalaran, Uldum, Dragonblight, and the Black Temple. Scribbled on the back is mention of playing Rexxar’s tale in Hearthstone Book of Heroes, and at least one match in both Battlegrounds and Arena.
Retrace their steps and you’ll be rewarded with two golden copies of Transfer Student! Good luck!
