In AH3 Waffle gave us a way to kill the spawn camp, you lay down a village object and set the spawn in the center. The large number of houses and trees beat the odds that you can see a just spawned in tank every time. Also, AH2, where all of our current terrains except for buzzsaw came from, most of the spawns were designed to be bad for incoming GVs I guess to create a pitched battle.
With the Euroterr set in the terrain editor, here is what Waffle gave us to make spawning in less of a suicide mission. Each of the three default terrain editor tile sets, Euro, Med, Pac, has an Atlas1 2x2 mile tile with a 1x1 mile village in each of the 4 1x1 sectors of the Atlas tile. These along with the three agriculture support Atlas1 tiles allow you to build "Civilization" around bases with realistic spawns in areas for your GV.
Spawns and how they effect an incoming GV are directly the "choice" of the player who creates the terrain. I caught myself allowing my biases against GV's and base sneaks by M3 to cloud my design process on my recent terrain. I hate GV's but, Gv's are a large part of the player base's fun. So I wiped my slate clean and started stop watching how long it took GV's to get anywhere. I started looking at our terrains after that and it was obvious some terrains the creator didn't favor GV's getting to town easily, some did, some wanted them to fight each other away from the town and field. And there were biases about base capture leaning towards pro defense and pro capture you could see in these choices.
Once a terrain is submitted, how it is setup is pretty much what you get. HTC does not build these terrains, a player like yourself does. So you are trying to persuade other players who you may not know , how to setup GV spawns on their personal creation.
In the screen capture below, the odds of being able to see a GV spawn in every time with all of those houses and trees is very small. Since you know the town or field is behind you, long range ambush them from the farm land as they leave the village. I'm not sure it's occurring to anyone yet Waffle created a paint by numbers ready made civilization to lay down around feilds so tanks can spawn in successfully and fight tank battles in villages with places to hide. Most are opting for the trees like AH2 that are whizzing off so many guys by stopping their GVs.
