Im curious as to why so many people can say that Rusty's limitis useless in the later stages of the game as I find saveing MP a great idea (you can just do a standered hit and it will do 9999) also to those of you who can do 9999 damage at the end of the game with special abilitys I ask you this: have you ever gotten Rusty's ultimate weapon? I find it hard to believe, if you can do 9999 damage then you spend way to much time leveling up, yes its nice to learn every ability but I ask you this: do you use all of them? honestly I think most of you will answer no because there is simply no reason. When I fight Trance Kuja just before the end fight ALL of my characters Trance so i do indeed find it very useful.

Word of the wise: dont worry about getting your ap just take it as it comes (and if you decided to ignor this then try fighting in the crystal against the bosses)
