I agree with Platinum. During the preparation phase I fished for 10 to 12 hours, both days, and secured a spot in 6th for the provisioner's list. I haven't done a stretch of fishing that long since I got my golden rod, and it definitely is unhealthy. The reward system doesn't help that fact at all. I know that when Limsa gets its hamlet, I'll be repeating my long stretches of fishing for a chance at that fishing hat, but I'm not looking forward to how it'll affect me.

Props to the OP. Very well thought out post.
