Oddly enough, there's some fights in this game where going all out is bad. Like Caedecus (sp?) in Turn 1 where he and his clone have to die within moments of eachother or it's a wipe. Or Bone Dragon in Crystal Tower where if the dragon dies before the skeletons do it's going to hurt alot. Or Laeviathan Extreme, I've been reading that if you try to burn him down he goes into an enrage causing a wipe. That's just three fights where caution is more important than how hard you're hitting the wall. Three fights of varying degrees of difficulty.
