As long as i get to be the frog
Aside from flavour or optimization there is a third reason why players may pick stats a certain way......Teamwork. They may pick a stat to be higher so as to not be a drain on party resources and not be in need of protecting/saving as often. They may pick a stat to be lower so as to not step on another character's niche. This reasoning for some reason does not get discussed as often as flavour/optimization.
Maybe, maybe what you are describing is just "team optimization". That's something these boards rarely look at because it's rare for a poster to know what the rest of the party is playing and ask for suggestions on what he should play.
