My thoughts:
- In an offline franchise, the user should be allowed to "cheese" like that if he or she wants to do so.
- What is the approximate threshold? I think this risk is tolerable if the approximate threshold of going overboard with editing CPU teams' players is known. I know NZA's PC editor allowed global edits, but then again that was the PC.
- Allow the option to remove the potential rating altogether? I know many people are frustrated that it "artificially" acts as a cap on season stats-based progression.
