Did you see any of the data mines? They literally time gated it so hard it will take months. Literally that bad.
Its not even humanely possible right now to reach 200 level crafting after they nerfed that twice.
Damn worse nerfs than I thought.
Watermark stuff
See the following graph. The simple version is this: The odds of increasing your watermark were reduced from 10% to 1%. Minimum GS increase is nerfed at higher watermarks (2 to 1). Odds of a 600 GS item dropping were reduced significantly, but odds of a 591+ is up on average. Overall, HWM progression is significantly nerfed.

Note there is a bunch of other stuff that also modifies this. It remains to be seen how bad the nerf is, but it will be significant. For example, HWMMult (a multiplier for raising HWM) was reduced from 30 on elite chests down to 15. For elite mobs, it was reduced from 2 to 1.5. For named mobs, it was reduced from 15 to 4. These HWMMult changes are on top of the drop chance being reduced from 10% to 1%, so there are multiple areas of nerfs.
Gypsum (edit with testing in NWDB discord)
An OPR cast gave +3 expertise. It is unclear if this is always +3 or if it follows the rules of regular HWM increases (i.e. up to +5 until level 520, then +4 until 545, etc.). Crafting an orb has a tax of 100g. Crafting a cast has a tax of 500g.
The gypsum, combined with the HWM changes, are the opposite of what the dev diary said. The dev diary stated :
But we have increased up the amount your Expertise increases with each bump to make Gypsum Casts and the random bumps feel more valuable.
However, this datamined info shows the opposite: The potential gear score increase is reduced on each step. There is even a new step at 585 where you can only go up +1, rather than the current +2.
