Seems the game updated the day after I downloaded, sorry for pointing out stuff you already fixed.
The cursed classes don’t need to be outright negatives, but having the same ‘power with drawbacks’ as cursed items is viable. And it lets you make them a bit more thematic. Examples:
Prisoners might give one damage resistance if they are wearing any locked gear, but reduce item durability by five percent. So they are stronger when imprisoned but more likely to end up in that position. Maid levels could give a tiny heal whenever a debuff is removed but slightly reduced resistance to debuffs, so they are better maids but worse every other class. That sort of thing.
