Waystin you missed another significant factor I built at that location.
One of the spawns was centered on a 150ft elevation looking down over the river to the airfield just at long range firing capability for tanks and M4 rockets. They controlled one bridge from that high ground. The land at the second spawn was slightly higher than the land on the airfield side of the river. The open vistas to tree thickets percentage allowed for rapid maneuvering and good concealment.
It's gamey but, GVers are more likely to come back against superior numbers if they feel like the terrain gives them an equalizer. And they did get a tank on the field with an M3 almost capturing the map room under our noses when we thought we had beaten them back during one of their many attacks. They owned both spawns into that field until our forces took back one of our feilds and saved us. Those map room on the airfield setups make for some vicious action if the owners want to defend. Even one guy willing to get towered a lot will hold up a capture against 12 guys like we ran into later after you logged off Waystin. Towns create lazy combat attitudes because the airfield is not the capture focus.
I got great data from that fight and the experiment in topography I placed there on making combat terrain inviting to GVers. I'm finding you only need to work with 100-200ft elevation differences to give GVer's a sense of being able to control their position. And Buzzsaw A2 has a bad GV spawn because it sets the enemy on a 500ft hill with a sniper hide to take down the GV hanger every time it comes up. That airfield needs to be rotated 180 to place the GV hanger out of easy sniper range. I did that to last night's field so it would take aircraft or ship guns to take down the GV hanger instead of a TigerII on top of a hill hidden in the middle of a spawn.
I really hate letting tanks sit on highlands risking nothing taking down airfields, in it's own way that's pandering just like Klingon cloaking trees. Many of the complaints about the GV game have a common impulse. GVers want to drive tanks around the AH combat zones like the muppets use to fly solo in K4's and dominate the arenas. To make that possible for them we need instant power-ups, Klingon cloaking trees, and Icons from the air that let wirbles rule because you have to get inside their gun range to see them. Now to keep them re-upping to keep a good fight going over an hour, it's obvious they want to sit in high sniper hides and risk very little with long range shooting. At least three well known GVers who don't care about not getting whacked kept up the actual active assault, got towered many times but, almost captured the field because they chose to fight and not worry about getting towered.
I blended the trees to grass ratio to enable fast assaults if anyone had the stones to attack at speed because those
bridges also split the defenders forces and focus. Wonder how many GVers know most of the bushes and all bamboo groves on Oceania can be driven through and the attackers were doing just that to stay hidden all the way to the airfield.
