The difficulty argument is not a good one since the normal raids are so easy they don't even warrant the gear they normally give, the accessories are the same as innocence ex but innocence ex is actually a proper fight with enrage and mechanics that actually punish you, although it's not the hardest at that. If we are talking about difficulty there is no way they warrant a whole 350 left side since they can be slept through, so I doubt square cares about that. I do find it odd that they don't also give weapons, but it's whatever, if you are not gonna do savage what is even the point of getting a weapon from normal raids?
