HTC'S call to change the regular V bases to pig pens seems to more encourage base sneaks rather than promote the TT battles Bustr intended.
I changed them to that because I had a sense Hitech would not allow them to stay tagged un-captureable like I initial set them to be. I didn't want to put a 1x1mile base object in that small of a location because it would promote hiding on the base and using manned ack rather than moving out into the pit to fight. As for the easy capture, ever wondered why I placed a GV spawn form the main island on the doorstep of each of those tiny vBases? Most of the time those tiny bases are captured by a single guy in an M3 who de-acks with the duce, then runs in the troops. If you want to keep it, you have to get out of the tower and fight for it in a GV.
I've watched the use of that TT drop to zilch as the Gvers choose to follow combat paths with the air combat initiatives. I setup the GV game on that terrain so they could revert to doing what they did with the AH2 CraterMA TT or be part of the flow of combat around the terrain. The spawn paths ensure Gvers can find combat, or play in TT, after that, it's up to them.
