Including a new dynamic to dayz with bullets being affected by; wind, temperature, pressure, and many other factors I think should be in dayz.
-For example: Having to use advanced equipment to find an accurate reading to get that first shot to be close or to kill. In the arma 3 ace there is long process to find an accurate reading before you take a shot (https://youtu.be/FT-FeSgiVFA).
-Players would have to find the basic stuff being a rangefinder and maybe a wind meter if you’re lucky. I feel some things from real life should be left out of dayz as it wouldn’t be fun for some players. Other factors could be angle of incline, bullet drag, latitude, humidity.
-Adding some of these variables would change up dayz gameplay and you could tell the difference between a good sniper and a novice one. An endgame item would be to get your hands on rare sniping equipment to be that skilled sniper or maybe just for practice.
-And this would make dayz even more realistic and give players satisfaction when hitting a target and further make dayz the brutal post apocalyptic game it’s meant to be.
