Because a lot of the characters I hadn't been using and they were pretty much useless.
That's your own fault for not using them.
This game features a quick and easy Party-Switcher. It's NOT that hard to press the L1 (or was it R1?) in the field while you're walking around to spread out EXP between ALL your characters. --- When you tour outside the U.S., Freezepop says to tell people you're from "near Canada."
People should know (atleast ones that play RPG's alot) that u ALWAYS and then I mean ALWAYS have to fight with EVERYONE eventualy in the game...
However I wasted the rest aswell.. Knewing it prolly would happen and it did.. Tho I didn't worrie because I just putted my strongest and weakest of my main party with the 2 I never use and the other team I putted my 2 mid main characters with the other 2 I never use... Easy duz it =P
