Patch 21.4.4 Is Out! – Nerfs to Omega Buster, Holy Mecherel and Recycling Wraith in Battlegrounds + Some Bug Fixes

Update: The patch is out now on all devices. Enjoy!

Blizzard has just announced a Patch 21.4.4, which will drop later today. According to the official social media accounts, it should be out around 11 AM PT, 20:00 CEST.

The patch brings three Battlegrounds balance changes – nerfs to Omega Buster, Holy Mecherel, and Recycling Wraith (but the last one is really only a nerf for Millhouse, unless I’m missing something). We’re also getting some bug fixes, including “general performance updates to Mercenaries”.
