I'm liking that idea: "All members have to level up for anyone to receive tokens."
Lock us into an association for the duration of the season as well. Draw is announced on Friday, SIX members in each association, not five, not four, SIX. Those six members cannot leave or be kicked out until the season has finished. Six level up = tokens gained, only five level up = sweet FA.
Sure, there may well be some who still just want to sit on top of the pile for bragging rights, but they're doing that now anyway AND getting tokens.
