After reflecting even more on the issue, I prefer FATE grinding to dungeon grinding TBH.

Dungeons are typically 45-60 minutes long depending on party. But you go through the same route every time. And if you get low level dungeon, it compounds the issues.

FATE on the other hand - each individual FATE is very quick. You can do as many as you want. And you get the freedom to do other things during the down time.

From a quality of life perspective, FATEs are much better than dungeon grinding.

Unfortunate... but if they're going to try to fix it, they should keep working on it until it can be considered fixed.
