Diablo 4's 10K-word patch notes bless necromancers and curse barbarians for next week's season 4 PTR

pcgamer.com:

Diablo 4 is about to become a wildly different game. Starting in season 4 and onwards, every class, item, and progression system will work differently. Blizzard has released the over 10,000-word patch notes for all the changes you'll be able to test out in next week's season 4 playtest, or public test realm (PTR).

It's hard to overstate how dramatic the item rework will be. The core of the game—of any action RPG, really—is the gear you equip and how it interacts with your class. Now that you can add stats onto Legendary items and significantly upgrade them through two new crafting systems, everything will feel different. Keep in mind that we won't truly know the impact of the balance changes in the patch notes until the new context they live in becomes clear.

At the heart of this patch is a fundamental shift to how items in Diablo 4 work. Basically, you'll pick fewer of them up, but each one will have the potential to become a key element of your build through two new crafting systems: Tempering and Masterworking. Tempering lets you attach unique stats on your gear, like a chance for a necromancer's bone splinters to cast twice, and Masterworking—which will only be available at level 100—lets you significantly upgrade those stats to your liking. The idea is that no two items will look the same.

Blizzard also combed through each of the classes and fixed up the most underused skills and the skills that kept some classes unbeatable in the meta. Sorry, barbarians, that means the big bonk that could one-shot bosses won't be nearly as big anymore.

Here are the most notable class balance changes in the Diablo 4 season 4 patch notes: 

Every elixir in the game will have stronger effects and a bigger boost to XP gains.

On top of that, Helltide open world events have been overhauled to have more monsters and a «threat» meter that will send demons to ambush you when it fills up. The Gauntlet, Diablo 4's weekly dungeon for high-score chasers, will now reward you with at least
