Woof... gotta reply to this!
Some of what you say is true, that the dogfight is the ultimate challenge and requires the greatest acquired skills. Latent talent is a big factor limiting many players to the level they can attain. A player can play for many years, some now approaching twenty, and still find it challenging with more to learn. Human to human contest is by far the most challenging, rewarding and enduring form or air to air combat, making games like AcesHigh so great.
But this isn't for everyone all the time, and limiting the game to air combat also limits the fun factor and player base. For example, a massive dogfight can soon grow boring if there is nothing to fight for. So base capture, base defense, strategic factors, historic accuracy and an objective serve to enhance the air combat... or it should.
The variety of other things you can do in the game, like mud pounding, ground action and sea combat provide alternatives when even the ace of ace gets tired of dogfights. For example, I (not an ace by any means) often use these alternate game play options when I find air combat too intense for my liking at the moment... taking a break.
I find that I only need one base to defend to keep me happy all night. I really care little about what's happening in the rest of the arena. If someone else is pounding one of our bases from a CV, that's fine with me. Everyone should be able to find the type of action they like, including milk run type stuff, suicide jabo, attack and run, cherry picking, space flight... whatever. Whatever floats your boat so you will give HTC your $15.
But I don't like arena capture because it messes things up for others. The most efficient way to capture bases is to avoid air to air combat entirely or use overwhelming force, to destroy and capture bases with impuninty. This is probably the cause of your complaint also. Rather than being the focus of AcesHigh, players complain that dogfighters aren't doing their part.
When your country doesn't have many bases left, it's no longer much fun for many. It shouldn't get to this.
