Fantasy vs. Science Fiction

Vis, if dragons are, in your opinion, invulnerable to energy and magic, fly at supersonic speeds, can teleport, have a thick layer of diamond scales, fly, have fiery blood, and are practically invulnerable, then how do knights with very rarely enchanted weapons defeat them?
Fire elementals are creatures born of fire.

What does it mean for a fighter to fire? To charge and shoot in a straight line? How does it hit?

I can't stand it when people, trying to defend their point of view, start engaging in such nitpicking and clinging to words and typos. You immediately understood that there was a typo here and it should have been "the fighter can fire."

I am providing arguments. Where are yours now?

Revan, Locke, and I have provided enough arguments; read the thread.
