Patch 21.3 – Battlegrounds Changes (Nguyen, Galewing, Shudderwock, Leapfrogger, Doomsayer, Smuggler And More), Duels & Arena Updates, Bug Fixes – September 21

Patch 21.3 releases tomorrow – September 21. On top of all the important Constructed changes (we’ve covered those here), Patch 21.3 also includes a ton of changes to Battlegrounds, as well as a couple of Duels & Arena updates and some bug fixes.

Battlegrounds players should be most excited, since the patch will shake up the meta considerably. Three of the most powerful Heroes (Master Nguyen, Galewing and Shudderwock) are getting nerfed alongside notable cards like Leapfrogger, Impatient Doomsayer and Whelp Smuggler. We’re also getting a bunch of buffs to underpowered strategies like Pirates and Quilboars.

In Duels, it moved some Passives that were performing too well to more rare pools and bans Voidtouched Attendant from deck creation.

In Arena, it disables Ramming Mount completely and makes a round of micro-adjustments too.

And finally, we’re getting a bunch of bug fixes, including some stability improvements.
