There's been more in-game fixes, besides yesterday's patch 3.1.1 and the long list of bug fixes associated with it.
Some of the more interesting changes:
- The Yogg-Saron encounter has received the following changes: Guardians of Yogg-Saron in phase 1 and Immortal Guardians in phase 3 have had their health reduced by 15% in heroic mode, the Destabilization Matrix cast by Mimiron will now correctly hinder the casting speed of Crusher Tentacles in both normal and heroic modes.
- Players can no longer summon the Black Knight unless you are riding an Argent Warhorse.
- Critical strikes from the Hunter ability Explosive Shot should properly trigger Thrill of the Hunt again.
The full list of the additional changes after the break.
