Wouldn't change much, you could still make as many teams as you wanted prior to R1. The people that are better at doing it start from round 1 anyway as it allows cash generation to get a better team. They just have each team set up specifically targeting the weekly prize of a certain round, for example the person who wins this round could of not played and have been targeting this round but you wouldn't know as the total points would still be acceptable.
Such as 17th place for this round just gone has played all 12 rounds, scored 5203 pts, and is ranked 60,207 overall. Somehow Miraculously had 11 DGW players scoring 1350, like 1/3 of his total season points, I imagine whoever has that account would have another one set up for this DGW round too.
