What do you mean by it? Almost all FC has gatheres and crafters in them, if you mean like FC with a lot of 4-star crafters in it then there are only a handful of them.

I am the main crafter in my FC and I have 3 other people who has crafter all level 50 or close to it. I have 3 4-stars and then there are other people who are the main gatherers. You 're welcome to join as a crafter/gatherer if you want to.
