*Have the option to shoot with both eyes open (for CQB), making the iron sighted weapon partially semi-transparent.
*Have reflex/holographic sights work more accurately (i.e. the reticle should move when the eye changes parallax, not be fixed like they are in Arma2, more noticeable with head tracking).
*Faster weapon reloads and quick sidearm drawing (especially for special operators).
*Randomly generated single/co-op missions like Wiper's fantastic "Cipher" (I must have replayed that for 200+ hours, being hunted and strafed by the MI-24V Hind is the best game-play experience I've had in Arma2).
* Can I please have a crosshair option that doesn't obscure my target. A large circle, or two horizontal lines with a generous space in between - -
* Being able to consolidate rounds from multiple mags into one mag.
* Remember my run toggle preference (I need to double tap shift every time I play)
* Integrate Valve's Steamworks for mods/missions like they've done for Skyrim.
* Not moving should factor into AI-player detection. You should not be detectable past 10-20m if you're adhering to the three principles of camouflage; colour, shape and movement. I.e lying down in long grass while being deadly still.
* Using low walls to prop weapon bipod or elbow.
* Being able to raise my head above an obstacle or grass
* Able to Toggle shooting handiness on the fly, so i can shoot with cover on my right or left side.
* Have mechanized crew AI turn-out sometimes.
* Improve grenade throwing, it's too hard ATM.
