The question is- do you want power gaming? If yes-destroy charisma for every one, excluding sorcerer, paladin and maybe cleric. It will make your charachters powerfull...brutes, that do not allow poor grandma to cross the street.
Fighters can work well with only 3 intelligense too. They do not need anything anyway.
Max strength and constitution wherever you can. max dex for rogue and max int for wizard, etc. IMPORTANT-sorcerer also needs high int. A 16 will do the trick or even 14. but no lower please. His magic boosting skills that he chooses are a blessing.
