The issue with doing AI CAS is the programming required....overall it has very little gain and more than likely the AI will end up hitting friendlies due to people running to the location and not being able to call off the strike as easy as a player pilot could.
AI FOB supply run is also not worth it. It is easy for players to make AI drive to the FOB already....I do it all the time. just make a group, control the AI and have multiple vehicles drive to the FOB at once.
having the commander have to capture the HQ wouldn't work well. what happens if they go AFK or D/C mid AO? a Commander also isn't a ground trooper. they would be at base controlling the battle not in the battle.
As good as the concepts may sound, they are somewhat unrequired as can be done already and the programming required isn't worth the hassle.
However with points being found, they could be something. Random unmarked missions on the map.
like 1 squad in a village with an intel pad on a table for points. 2 vehicles driving around a location that need to be destroyed. Even maybe a small attack on FOB/base which defended gives points.
Points should be more just giving assests or even the choice of between assests at end of a Side AO.
