Only 2 to go after you volunteered!
So you meant that if one team would become "a challenger" (which takes 15 tokens), that doesn't have that many tokens?
That would truly be a problem... And that's why we try to find volunteers (2 more).
If we won't find volunteers, then we need to likely resort with the old plan, so that everybody sends half of their challenges. But I still think it streamlines things if half of us would do that, and other half just accepts all the offers. Now that the responsibility is shared, it's more complicated and especially more prone to errors in some sense.
Also, it would be way more arduous to edit league schedule with BB forum text editor tools, whereas if we choose 8 challengers-option, we can just mark those responsible for sending challenges to a team name list with a simple sign, such as *C* (or whatever we'd choose to use).
