Vent: My fantasy world felt empty until a prompt gave it LIFE, now I debate reliance

I was building a magic system and my characters just WOULDN'T connect, it was so frustrating. Scrolling through prompt lists, one about 'a gift that curses the giver' sparked the entire backstory. But I've heard writers argue that overusing prompts kills original voice, while fans say they jumpstart ANY project. Honestly, figuring this out saved my book, but where do you draw the line?
