If you want to discuss GMod, realism is not a valid argument in the slightest. I mean come on... numerous classes are bullet sponges and eating sniper shots is a daily occurance. Also, unless you are constantly recording we have no way to enforce this. What constitutes jumping in combat? What if they are jumping to cover? By all means if you want to waste 10 minutes uploading a 30 second video for an admin sit, then getting sent back after a verbal is handed out by all means. This would be the most unenforced rule since the whole "SCPs need to advert when they breach" was a thing. All I see coming out of this is more toxicity in OOC where player A is like "F***ing jumping in combat" or "NICE COMBAT JUMPING (player)," and player B just doesn't respond or makes some equally annoying retort.
