Though, later on in the game, such roles may seem arbitrary (by the end, all of the characters are virtually the same),
yea very true all my characters do roughly the same damage if they have the same weapon equpied(9999 if its excaliber or the zodiark spear)
same thing happened in ten also cept from closer to the middle of the game
anyways im babbling, some advice- if you want to gain loads of LP easily jus go back to the first or second areas in the game(estersands and westersands i believe) and slaughter your prey
most monsters give 1 lp anywhere in the game so you can rack up lots here quckly and safely
