Yes, things like that certainly could happen. But that would only happen if a player views tournaments as the only reason they are staying - because they left due to not being able to join another tournament. That could be i guess, but since they can only join one at a time (and i'm assuming it would this player's first tournament) why would they leave just because they cannot join another tournament? None of this affected me because i was a rook before tournaments or fellowships got introduced, so i guess i don't really know - maybe you would have a better idea than me.
