If you count TTRPG classes, I've heard bad things about the Truenamer from one of the later D&D3.5 sourcebooks. Basically, you have to make a skill check to use any of your abilities, the DC of the check goes up by 2 every time you pass it (resetting on a long rest), and level scaling increases the base DC faster than you can increase the skill.
You either minmax that one skill and mostly suck, or never meaningfully contribute to any encounter, ever.

That guide is a work of art.
