Would working your way up strictly to a 125 str. give you any advantage keeping the others at 10? Or would it be pointless and you might as well raise two or more at the same time?

Thing is, I know the limit is 125 in any ability, but if someone sacrifies dex and int purely for str, you would think there would be some sort of benefical award.

Even the crazy idea of a 205 str with 10 dex and 10 int, would the character have that much an advantage? He can't cast spells and he can hardly hit anything.
