Fantasy League: The Amount of Teams

For Fantasy LCS, we should be able to have 5 teams. I know we can have 5 teams by choosing to have 6 teams, but then we have no person to fit in the 6th spot. Also, drafting can't start unless all spots are filled. Riot please make it so we can have a max of 4, 5, 6, 7, or 8 teams.
