I know I'm a n00b (of sorts). But....
I don't get what the argument is about.
Aces High has a built in overlying scenario... Capture the base. A horde can capture a base better than one or two fighters on their own.
How about, instead of trying to convince the "horde" to not "horde" in, convince your own countrymen that that huge bar-dar needs some attention?
A part of the reason the "horde" is such a big problem is, even when someone spots it AS ITS TAKING OFF and with plenty of warning, NO ONE helps in defense. So the 3 or 4 kind souls who actaully paid attention to the multiple "Large numbers of bombers and fighters, upping 11 heading A6" calls, get slaughtered, becuase those 3 guys were defending against a "large number" (which in at least one case last night amounted to 8 fighters and 6 17/24 groups).
You're not playing a 1 v 1 online flight sim. You can use the HtH option, or dueling arena for that. The Main Arena is a MASSIVE MULTIPLAYER area, and so therefore, you have a "massive" amount of players, styles, and personalities to account for. You now have the possibility of intelligent wingmen to fly with, and attempt to thwart attacks or create your own. If the idea was nothing but A2A duels, HT would never have made bases, troops, VH, HQ, etc, etc, etc, captureable and destructable.
Again, maybe my misunderstanding is because I'm "born again new" so to speak. But even in beta you'd have big groups attacking one place. It was just more common that a competing group would up to help take them down. Now, everyone always seems to be off doing their own thing.
