Well, I feel compelled to point out that, while there are inconsistencies in certain aspect of GV play, HiTech has not completely ignored ground combat. It may not be getting the hightest priority, but it's coming along.
1) The killer trees and buildings have been fixed.
2) The damage model made more complex than when it first came out (all-or-nothing damage model giving way to multiple damage types).
3) The addition of resupply/repair of GVs in the field.
4) Addition of man-able defensive guns to oppose GVs.
5) Addition of barriers and destroyable structures to the terrain editor library (have you
seen the tank-battle villages in some of the CT terrains, like Fin-Russ and Rhine?

).
HiTech has also said he is working on overhead concealment for them as well, such as forest canopy that you can hid under. Plenty of other GV bugs have been quashed as well, albeit rather more slowly than some would like. I for one really enjoy taking GV's out (though planes are still my favorite). Are there problems still? Sure. Are they in the que? Most probably are.
