It would be interesting to see weapon scope calibration implemented in DayZ Standalone. You could adjust the scope (maybe also iron sights) properly, and the adjustment could misalign while crawling or when receiving damage to the gun, so you would have to test it every now and then. Weapon oil, etc. would be funny, because unless you didn't maintain your weapon, it could malfunction when needed. :D What do you think guys? Instructions could be given in an in-game book, for example.
