-Most of the high level spells in Super Mario RPG don't do appreciably more damage than weaker spells or even normal attacks, and are absolutely not worth their sky-high FP costs.
-Megid in Phantasy Star Online is semi-useless thanks to its low activation rate against most enemies (it's a one-hit kill attack, but its activation rate is based on how low the enemy's EDK stat is; in Ultimate difficulty, most enemies have an EDK high enough that it's far faster to just kill them the normal way).
-If we're allowed to go with entire classes, both the Sniper and General in Fire Emblem have historically suffered from this. The former would be amazing in a game that didn't include counter-attacking; the latter would similarly be great if the game design included more defensive maps instead of ones that expected you to move against enemy positions, often penalizing you if you take too long (by having recruitable characters get killed or enemy thieves loot treasure chests, for instance).
