Obviously, you have never outfitted Malak and Rafa correctly, they are amazing! I can kill the final boss with just those two. Agrias is just annoying, i can't stand her, i'd rather have had Gafgarion. Mustadio is worthless after you get cloud, i never used his snipe abilities anyways, I never saw much of a point for them. Besides, I like making their brave story say they died somewhere, it makes for dramatic affect.
