That was in announcement #1
Announcement #2 changed up things a bit, let me have a quote:
That being said, we will make the following issues our highest priority after the release of the new features:
Farming and grinding for high level rarities
So we shouldn't expect any gear grind revamp at least until September. Oh boy it's gonna be fun, since we'll have 3 chapters for older servers, and 5 for newer ones. Without any grind revamp.
