mostly useless spells

[Mercen-X]

Full Cure in ff7 was dumb when you could just W-Item up a few Megalixers.

Consider that FullCure is obtained sans long boring trip down dark tunnel full of monsters that silk you till you stop wherein White Wind is only useful in preventing the actual stop because the slow and other stats are immediately inflicted again... it's just damned tedious. Also, Megalixers..? I personally don't prefer to rely on a non-canon glitch.

How about Demi or anything Gravity-based in FFVII? Pretty much all bosses are immune to Gravity, and in random encounters you don't really need to use big spells anyhow, making that whole element pretty much useless.

There's an enemy in there someone that Gravity causes instant death on. Like Poison against 8-Eyes. I only found it recently. It was simul-neat-stupid.
