A lot of headaches w/AI could be solved if BIS developed a AI control scheme similar to a real time strategy. Give us the option to assign waypoints to our AI as well as advanced commands like what stance to have at a waypoint, whether to be aware, combat ready, etc, standing/crouching/crawling, and more all from the map mode.
A similar comparison would be high command in Arma 2, but a lot more polished.
I don't see how this is a hard thing to implement and it would be a very useful feature.
