The first rule of Fights thread is don't talk about Fights thread.
The second rule of Fights thread is don't try to overdo the realism. Most games aren't even close to being simulations of actual combat, and nor should they be.
The third rule of Fights thread is get your players to do most of the work. Those lazy gits are mostly just rolling dice and eating Cheetos, so get them to take on some narrative duties.
The fourth rule of Fights thread is use a three act structure dinkus, it works.
The fifth rule of Fights thread is don't use too many words. Sorry, what? I got bored in the middle of what you were saying there. Be fast and furious, make your prose match the pacing of the scene. Fights scenes aren't the place for the DM to wax poetic.
Anyway, yeah, knowing something about how to write a fight scene can help you adjudicate one better.
