You continue to astound me. Mindless beasts of that magnitude exist! We have them. We had more in the past. Dinosaurs, woolly mammoths, gators, sabertooth tigers, anacondas, bears! A binge eater only needs to eat about 8% of it's body weight. That's one cow per dragon. It wouldn't decimate entire herds. With my type of dragons there would be the exact same type of civilization. You don't see bears destroying society, or anacondas, or gators. Occasionally they kill someone, but society learned to live besides them. You need to comprehend that a "monster" is nothing more than an animal we don't understand/ are afraid of. Realism in fantasy is not some sort of crazy thing, it just means placing limits on the degree of fantasy. You don't have to like it, but to me it adds depth and complexity to fantasy universes and makes them more believable. You keep your lame ass over played super dragons that can do virtually anything, yet for some reason still manage to get killed and don't rule the world. I'll keep my dragons as predatory animals in a limited fantasy setting. You know what makes it fantasy? DRAGONS! They aren't real. You know what makes it realistic? They're ANIMALS and behave and are limited as such.

I also think magic ought to be limited as well, and that the idea of races as inherently evil is a trite oversimplification of the idea of evil, but I imagine that would just baffle your mind too.
