The best thing HTC could do is figure out how to encourage game play without promoting 30v1 odds. There are 100's of ideas out there and I'm sure HTC knows of most of them.
The horde is a product of wanting to be a "winnah", regardless of an individual's actual contribution. The bad thing is that the entire Aces High system is designed around attacking or defending and actual airfield. There is no neutral ground to battle over. There are no towns (think Bastogne), strategic plateaus (think Kursk), or island (think Guadalcanal), to do battle over, around, or on. Everything centers around a base. So when the horde arrives at a field, there is no battle because there is no chance to defend it. The importance is to take that field. Just how often did the battles happen directly over an enemy base? More often than not it was an engagement.
The horde is quickly becoming a huge downer to a lot of people, me included. It is worse now than it has ever been, and I've been playing since Jan of '08. I remember lots of smaller capture missions in to a town with 8-12 attacking aircraft, that wasnt too hard to defend. First, the field was not leveled. Secondly, the odds didnt seem to be 20+v1.
IMO, HTC needs to rethink a lot of things. Hardness of OBJ (concrete ord bunker and playwood barracks are the same? Huge bomber hangers are the same as small motor pools?), ENY values of aircraft, perhaps tweeking the town setting (remove the flag!!!), burn rates, HE damage from tanks, high speed heavy bombers (need a max speed for level bombing), etc etc.
