(yes, i'm sure there are a few situations where they can help you, but that's getting a bit contrived).
Not at all! It's the best way to stop the Condemned status.
I feel the issue is more the Remedy spell than the Dispel spell.
Remedy item: Lifts Dark, Poison, Imp, Petrify, Mute, Seizure (Note that Imp is cured with the item but not the spell. )
Remedy spell: Lifts Dark, Poison, Petrify, Mute, Muddled, Seizure, Sleep, Slow, Stop (Cures Muddled, Sleep, Slow, Stop, unlike the item.)
Dispel spell: Lifts Clear, Image, Berserk, Regen, Slow, Haste, Stop, Shell, Safe, Reflect, Life 3, Float
It feels like the Remedy item cures all physical ailments and Dispel the magical ones. It's de-spell, it removes spell-induced effects. FF6 just ran with !Special attacks, making lowly scorpions set Stop and all. Anyway, there is no overlap, and the only statuses they don't cure between them are Muddle and Sleep, both cured by the physical strike instead (also Zombie and KO). The Remedy spell just does whatever. Why doesn't it cure Imp? Why does it cure Slow and Stop? Why cure Muddle, but not Berserk? I'd just make it simulate the Remedy item, possibly curing Muddled and Sleep as well.
Also, what's the point of using Dispel outside of battle? In that situation, it can only remove Clear and Float.
I'd propose a fix, but how do you remedy Remedy? An impossible, self-defeating concept.
