Tropes are often used, not because authors are lazy, or unoriginal, but because they just work. They can explain things that are complicated topics encountered often either in reality or in fictional words. A quick example that comes to mind is the main character is an outsider just looking to be one of the cool kids.
Ready for the hot topic of the night? Pantser versus plotter: which way is right? Which way is better? My answer: no. Wait, what? That's right, you're already doing both. I can explain, but then you better start working on your story. The world needs books, not debates.
