[2022] Using Gypsum to go from 590-600 after patch

I have reached out to the team about this and they have also heard this feedback loud and clear. It is currently being looked into.

Gypsum Casts will be a guaranteed method to get you Expertise bumps from 590 to 600 once the patch goes live. So if you are capped at 590 already in all slots, saving Casts until the patch drops is the best use of them.
