So, this is a tricky question to phrase right. Are there any characters you wish you could find more reason to use, but can't really find logic to use besides very specific situations? This could be because of viability, them being outclassed, a lack of good gear, or maybe they're better but don't have an MC2 in your version.

NOTE: Obviously the game isn't so hard that you need absolute min-maxing and could use your favorites most times, but this is mainly concerning those who want better for a favorite or well-liked character.

For me, it's Luneth and Snow. Luneth is one I like, but since I got Zack's Buster Sword the latter almost always fills the role I need given similar skill sets and more common synergy. Nothing bad about Luneth, but for optimization's sake I usually run Zack.

Snow I don't know too well from XIII itself, but I just kind of like the idea of a bulky Monk/Knight character. However, Gilgamesh (another I like, but he's already great) pretty much fills most spots I'd need him for since he can use Fists and more (I have few Daggers to give Snow RS options Gilgamesh wouldn't have), has Knight 5 too, and there aren't good Monk skills to give Snow a niche over Gilgamesh. this is more wanting to experiment with Gameplay but not having the means or a reason to.
