Diablo 4 patch 1.0.3, which was out today, June 27, 2023, has introduced a significant number of balance changes to the game, along with fixing a majority of the performance issues. Some of the biggest highlights of the patch are the massive buffs that have made their way to almost every class in the game.When talking about the balance changes, Blizzard mentioned in their blog:“We’re continuing our efforts to make all Class builds feel fun and powerful with another round of balance updates. In particular, we have seen community feedback stating that Basic Skills aren’t impactful enough in combat. These changes will not change the fundamental relationship between Basic Skills and Core Skills, but we hope that they help smooth out the leveling experience while we explore additional ways to strengthen them”They continued:“We are also increasing the power of some Skills that players feel are lagging behind their peers. As we look forward to future updates, we’re monitoring other heavily discussed topics, such as Minion survivability and build parity.”Below is the list of all the balance changes that have made their way to Barbarian, Druid, Rogue, Necromancer, and Sorceror in Diablo 4Diablo 4 patch 1.0.3 (June 27) class balance updatesDiablo@DiabloWhen you've outrun your outer demons this week, but your inner
