I agree with this, except for the radar, I believe it should remain as it is, except for the HQ problem of course. With permanent-radar there would be loss of purpose in strategic targeting of radar towers in the game. IMO it would make things too easy-ish
It's no different than modern military strategy - they see everything on the ground and in the air (for the most part), yet strategy is still required 100% of the time.
In the current Aces High, there isn't much real-time strategy. You try to guess what targets are undefended, and try to guess where the enemy is and where he's headed, and then come up with a plane you hope will work based on those guesses. It's not very effective. Once the enemy is over a base or within your radar ring, sure, you know where they are; but by then, it's almost entirely reactionary.
What you end up with, in a 100% radar environment, is instantaneous strategy. You know where the enemy is massing, and you know where your guys are at, so it actually ends up being a much more dynamic, RTS-style strategy, where you are actively moving forces around to directly counter your opponent.
In the current Aces High, you might see a darbar two grids over, but you have no idea if they're heading to CAP your base, or hit the vbase north of you, or if they're simply bombers climbing to hit a completely unrelated target.
With radar on, you can see the fighters heading straight for your base, which allows you to call up all of your fighters and head them off. In turn, then enemy can see your opposing fighters upping, and they adjust.
It's completely dynamic and results in a much more engaging fight and playstyle.
