Good worlds will have low turnover, and will have new owners already lined up to fill any openings when the world rolls. That's on the commissioner to ensure both of those things happen.
Sounds like that's not the case with FOD.
If you have high turnover (8 is fairly high), the commish needs to understand why that is happening and "fix" it. If he's not doing that, then he's really not doing a very good job. And the rest of the world suffers for it with long wait times to start.
