Just want to know if one league have a rule like....if you finish in the worse team you are out.

I've seen it pitched and I believe the short lived Village had the rule in place

Paydirt B had an elevate to Paydirt or be bounced element.

I've seen it a lot but eventually is it cool to boot peeps from leagues + hard to keep leagues filled as it is without forcing to get a win to remain in a league.
