The problem isn't the bad guy knocking down my hangar (like you said, I should defend it better). The problem is the "good" guy doing so.
Knocking down the FHs accomplishes a few things from a "good guy" perspective:
1. It forces ALL enemy fighters to up from a distant field, and have an Alt/E advantage when they arrive;
2. IF the base is quickly captured, it means you can't up fighters from it for a few minutes (and if it's so quickly captured, why did you need to knock down the hangars?)
3. It generally leads to an exodus of the better fighter types (I'll hang around a base capture, but I'm not hanging around for sight seeing)
Really, from a "good guy" perspective, knocking them down just doesn't make that much sense. At least not usually. 5k "Malta" bases like the one in Trinity (A5 I think?) being the exception to the rule.
Agreed on all points, but especially the second one.
Base capturing and missions are good for the furballers, also. As I've stated before, it gets defenders to up. I am more than happy to follow a mission. I'll even take some ordinance with me, drop it on town, and then proceed to help cap a base.
If the real estate guys want the furballers to put up a cap for them, than leave most of the base buildings intact. If you drop all FH, and try to continue the momentum to the next base, it just wont happen. I, personally am not in the habit of waiting for the toolsheds to come up when there is probably another fight going on somewhere else.
