Sorry for the double post, but I thought it best to get people's attention about this bit of news. Fatigue has been confirmed to regenerate when you're not actively leveling a job. Fatigue just resets regardless every week (apparently in a similar manner to campaign tallying from FFXI on Sunday mornings).

This seems to me to make fatigue a relative non-issue. Sure, you have zero exp. gain after fifteen hours, but just do something else (idle on another freaking job?) and then go back to it. If people are *really* upset about having to do something else in game after fifteen hours of grinding to let fatigue cool down, they really need to be doing something else with their lives.
