You only addressed part of the issue. As long as a single set of bombers can take down the HQ and downtimes & resupply system are what they are now, you have one single player being able to perform the by far most disruptive attack possible all on his own.
In my book that's just wrong. It should take a comparable massive amount of effort to destroy it , it the effort should at least somewhat scaled to the outcome.
When there are like 10 or even less active players in your country (yes, that's real numbers), you will often be hard pressed to get up any HQ defense at all, even if you can now see him coming all the time. Even then you have to take into account that actually many players can't afford a Me 163 at all. When there are 200+ in the arena, you'd probably right with "they should have defended" if the HQ was in a non-NOEable position. But with 30-50 players online total (of only a part is actually active at all), this is just illusionary.
So there's a single raider taking down the HQ for maybe 100 minutes. With so few players on, you can about forget resupping it under the current system, unless you put all of them in goons for a long time.
Harden the HQ to much more than 37,500 lbs, or cut the connection between city or HQ or find a different, less overall disruptive effect.
From your response (minus the first sentence) my suggestion completely addresses the issue (no partly about it). What you're saying is my suggestion isn't effective enough (surrounding the HQ with dar rings, ack and fields*). All you are doing is trying to drag HT into making the HQ take more bombs on top of that. Well ok then. But I don't see the necessity. In other words, to me, this is just one more 'Hey look. The sky is falling and its all HTC's fault. Game'll be dead because of it.' threads. Meanwhile Dale and co. are busting their collective tokusi to code us new graphics after which, iirc, so many threads telling us the sky was falling and its all HTC's fault because they refuse to make the game as pretty as WT (a game most agree doesn't hold a candle to AH, overall) spammed the forum (my advice to the masses - play more, whine less, post something more productive).
I've watched this thread go from -
I logged because I couldn't find a fight during off hours when someone took out my HQ.

Well, I might coulda found a fight if I tried a little harder but what about the new guys (as if we were never once)? They'll log quicker than me! Sky is falling - all HT's fault!
to
HT can fix this, we can't! (Even if, really, we could. Map makers can make it just as hard to bomb the HQ as HT can.) SKY REALLY IS FALLING! IT'S THE END!
*Remember your map example? There was that corridor for the sole porker to take advantage of. My suggestion addresses specifically that.

Now ..... I'd like to suggest all take a collective breath and think for a bit. This has been the HQ by design for awhile now. It's nothing new. Even a new guy should be able to wrap his noodle around it. The sky isn't falling. This isn't the end.
But .... someday this game will end. More than likely it'll be a tired Dale announcing Aces High is shutting the doors. He'll be professional, business-like and friendly about it. I can't help but think, though, (and it's just my take) that the thought 'You can please some of the customers all the time, you can please all of the customers some of the time (that's a rare miracle- usually countable in seconds) but you can't please all of them all of the time no matter how hard you try.' will have happened often enough to influence the decision (at least speed it up, maybe). Would me, you buncha ingrates.
