FATE Grinding = Not learning?

[Billie21]

FATE parties are "PARTIES", not group of people who doesn't care

They could (and can) be.
Most of the time though, it's the opposite.
What is sad, is that the game rewards the later as much, if not more than the former.

From my experience, you are the exception to the rule. At least in the regions with big rewarding FATEs.
