I understand this series of logic, it's been touted to me time and time again. But it absolutely doesn't change my argument of human level roleplaying. I'm not talking about mid tier, I'm talking about flatline human level combat. Using only real weapons and real human abilities. 

Let's break it down piece by piece and try to tear apart this argument that I keep running into every time I bring this up.

1: Impossible to dodge? Yes. Impossible to survive? No. If you can't dodge it, survive it. Where YOU get shot is up to you. Plus, Humans have this keen little ability to move faster than the hand of another human. We do it all the time. Don't dodge the bullet, avoid the line of fire entirely. If you're fighting against a person who HAS a gun, and don't HAVE a gun. You should be prepared to have to dodge and weave, serpentine and roll. Cover is totally up to the game master or players, relying solely on a flat plane where you fight your opponent is stupid. No matter what weapon you're using, a flat plane doesn't really exist in real life. Save for maybe a city street, but even then you've got windows nearby that you could leap into.

Giving the enemy every advantage, giving them what basically equates to a shooting range is stupid and your own fault for agreeing to it anyway. 

2: This is true, entirely. I can't argue the sheer ease of using a gun, it's simple to point and click someone dead. People do it all the time, there's literally training programs to show you how to do it better. Though to mitigate this point, please refer to point 1 and 3.

3: Yes, the damage of a bullet is substantial. EVERYONE understands that. However, the damage a human body can survive by simply being durable is just as much as most bullets put out. This has been proven time and time again, with the numerous cases I just listed. And as I stated before, just because people HAVE died to guns before, doesn't mean that they WILL die to guns. No matter how normal a human character IS, they're still more than human. The writer knows what the character does not. A great writer can, yeah, sort of circumvent this. But a competetive writer doesn't want to circumvent this, becasue it means they're going to lose. So instead of just giving them this shooting range where the marksman has the total advantage, you give a REAL battlefield.

This is the thing so often overlooked by writers in the Arena, but never overlooked by action movies and shooter games. An absense of cover is suicide. A realistic amount of cover is, well, realistic. 

If you don't want guns to be overpowered, don't LET them be. Don't give them a shooting range with a slow moving target that drops in a single shot.

Give them a setting with a human that can survive a shot or two.
