A couple of suggestions, HT:
* I understand the need for moving targets such as convoys, and I must say strafing supply trucks is a real hoot in aircraft. But in a GV perspective, the 60mph travelling trucks are very hard targets to manage.
So, how about if a hostile GV blocks the road, the trucks stop moving when it meets the GV?
* How about roads giving an advantage to GVs? Something like 'vehicles will travel 3mph faster when on a road', or 'vehicles can land safely on a road, if no enemy presence nearby'?
The point of these suggestions is, the road system, coupled with the forests and terrain features make a really beautiful scenery.
Currently the GV battles are mostly "open-space battle", where GVs meet in a wide space, which is ofcourse very fun. But having an opportunity for different kinds of GV battles - road fighting, blockade busting, and forest ambush and etc etc.. would be very fun.
If there was some logic to compell GVs to use roads, or tempt the GV to blockade the road, then it'll provide great opportunities for GVs to fight at some critical points of the road.
