My Idea is for a Variable Front, where GV's could spawn in any territory you control, not simply at a "spawn point"...
The Terrirory you control is based on the location of friendly and enemy bases around the map. The default line is equadistant from one base to the next, making the distance between the line to the friendly base the line to the enemy base the same. But as two or more tanks advance the line moves, allowing your tanks to spawn closer and closer to the enemy base (single tanks would not show). If enemy tanks cross the advanced line, a grey zone apears where neither side can spawn. Some may say that this system would cause GV usage to go down as the distance needed to drive would be much longer. But if they added gliders which could transport light tanks, jeeps, and artillary (when we get them) like the ME-321 and CG-4A. They could set up a forward GV base with one hanger and could be destroyed with 10 troops just like a regular base.
The idea for a variable front could also be used for PC ships and subs...
