I agree with Vinkman that something should be done re spawn systems..............
If I may I have always liked the idea of "spawn roads"
In RL gv's travelled along roads and then deployed into open country side to attack / defend so I like the idea that they should still seem to travel down roads which on the terrain would be seen exactly as they do now.
Vehicles would always spawn to a road but not always in the same place and indeed the player spawning could choose roughly where he/she may spawn along a road.
Each road between two bases being divided into sections.
On the map the roads may look like this and they would be interactive with the mouse such that a double click over a section of road would spawn the gv player (from the tower)somewhere along that section of actual road in the terrain.
The road section(s) closest to an enemy base would not be available.
A player can only spawn along roads connected directly to his/her origin base.
A player returning to his/her origin section of road can "land safely"
If it is clear that one section of road in under ambush (camped) then players may choose another section of road and make progress to break the ambush.
