I think Arma 3 should add a better way to make load out by adding a button to unit placement (F1) menu, this would be extremely helpful towards mission developers and to mess around in the open world. The reason building placement should be included so people can make their own pier or airfield, the possibilities could be endless. Maybe a built in map editor like Farcry 3 so people don't need to learn all the tools when everything is laid out as easy as possible.
