There are a lot of things that are already posted i agree with.
*I would like to see some more realism in Camougflage(it already was pretty good).
*More artillery(the were only in the game in ofp through addons) so i would like that more. This would be a great improvement if it would be a 'Nam based game. cause in that war ass you all might know the US firepower played a huge role.
* Another thing i would like is a more advanced damage system. Not only for better and more versitile damage graphics for different weapens. But also for vehicles more accurate damage. ( so i you shoot a chopper in de engine or such that should be damage, not just a bit of the damage bar.)
* And i also hope it will be possible for bigger online gaming, without a huge increas of need internet speed.
Hope people will agree with me especially Bohemia studios.!!!
