I would have to agree that this idea should be seriously looked at. The HQ should play a mojor role in the game instead of the weak role it plays now.
I would also add that the zone bases and the strategic targets, i.e. troop barracks, ammo factories, radar factories, and refineries should play more of a role than they do. Maybe harden the radar towers at the zone bases, and then let them control all the radars for that zone, like the HQ does for the country now.
Example: Take out the radar tower at the zone base and radar coverage is diminished by 50% in that zone. As the radar factory is damaged the % goes down further in that zone. Make it so it takes 10,000 pounds of ords to kill that zone base radar tower. It will still require a directed effort to take it out. Make it the same for all the zone base strat. targets.
The HQ should be the ultimate prize, requiring a concentrated effort to capture it.
I like this idea, because the important targets will have to be hit to win, and they will have to be defended to keep from losing.
