They do not HAVE to change anything. Preference points (PP) simply put you in a group with all others with the same number of PP. In theory, 2022 could be 100% draw with 3 PP, 2023 could be 90% draw with 3 PP, 2024 could be 75% with 3 PP, but that does not "force" them to change their system.
A certain percentage will never top out at 3 PP because they will take their chances (possibly better) with 0 PP.
Additionally, no one loses PP when not drawn. No one loses money when not drawn, unless you consider the application fees and base licenses that are not refunded for non-draws. If I don't draw this year I'm still considering Antelope, Deer B, turkey, upland birds, coyotes and badgers.
