You forget we live in an era where games are built for the lowest common denominator.

Though honestly, I would argue that the best party set-up in XII is debatable. An adequate story beating team would be simple to surmise, but an actual "best party" configuration would be a bit more difficult to determine. It would really come down to play-style and whether you feel it's better to rely on Reverse spells and Bubble spells or simply rely on the inefficiency of shields and Bubble Belts can give to a party trying to deal with stronger marks and the games end bosses. Not to mention debating about the best set-up for maximum damage. I seriously end up having to switch from a mob killing party and a boss killing party, cause neither set-up is efficient enough to do both jobs well for me.
