I've been reading up on some of the algorithms used in FFX, and from what I can tell it's next to near pointless having an Agility beyond 170, since after that the tick speed of your character won't get any higher. Is there any truth in this? Can you really get away with 170 Agility, or does it serve another purpose? I'm going to try and optimise my characters so if I can get away with saving up some nodes for HP I will do.
