I think that ATC is great idea, but... it will only work if:
Pilots have to follow it
and that there are separate, TFR/ Teamspeak channels for different roles
ATC helps to organise the chaos of getting troops and supplies to and from AO's. Also having ATC would also let noob pilots who are less experienced at flying an easier time as they would have more space and time to maneuver at HQ.
Just my opinion but I super hope we do something like this and I am 100% in support of an ATC!
