Guys, develop proper 3D scopes using PiP or whatever and release it as a DLC called "Situational Awareness".
Proper 3D scopes will cement your position as the hands down best tactical shooter available and go a long way.
I've played over 4000 hours of the ARMA series and am a student of military history, tactics e.t.c. and I believe one of the last things remaining missing from the ARMA infantry combat system is 3D scopes. It used to be use of cover too but the ARMA 3 stance system changed that and the adjusted recoil system is pretty much on point.
Just do it guys. I know you turned over a 100 million with ARMA 3. Invest in your products future.
P.S. I just remembered you also have to find a way to render grass at distance or somehow translate the additional camouflage effect at distances.
