Gathering Fates

What if the Gathering classes each had their own Fate.

For example, while you are out chopping wood or gathering supplies for a certain craft an unusual looking circle would pop up on your map. It looks like a fate but it is another color all together. Like pink or something "flashy" that would stand out. You go over and find out that you need to get your pickaxes or fishing poles ready because it is a gathering fate. When you complete it you will get an extra boost in exp as well as collecting a rare ore, fish or even wood that you couldn't find anywhere else. They would act as a regular fate, but only with this minor twist. Like all fates, it would be better in a group. But can still be completed alone if you are a high enough level in that skill.
There is still room for better ideas but this is just an outline of what i thought would be cool to see in the game.
