Taking this discussion to a more relevant thread
I find that having green air is incredibly useful and important, especially against the Allies who love to strat bomb.
Green air is whatever to me. Green air won't capitulate the enemy. Green air won't stop enemy divisions from capitulating me. Only boots on the ground can do that. Green air is only going to be a supporting element, a force multiplier to those boots. Instead of spending all of the extra research and industry on fighters to give your boots a friendlier environment, why not just put all of that into having better boots? 2k Fighters at an average of 25 IC per plane is going to be 50k IC, which could also have been 4 or 5 medium tank divisions. I think that the 4 or 5 tank divisions are going to have a much greater impact on my operations than what the green air by itself would. Red air is going to be a penalty to my movement and defense/breakthrough, but that can be entirely offset by divisional AA which is often going to be cheaper than what it costs to establish whatever level of superiority penalty. You only need 2 MSPAA2 with +5 gun to get the 112 AA value needed to ignore 35% of the superiority penalty, which is the basic maximum before doctrine and other boosts. That is only 288 IC and 2 width out of any division you care about protecting. Any amount of divisional AA, even just support AA is going to be cutting enemy CAS damage down to 1/4th of what it would otherwise be, and shoot down their CAS. What else is there to protect against, other than strat bombing?
You need thousands of bombers for strat bombing to be anything more than an annoyance. Between dispersed industry upgrades and some state AA (as well as just bum-rushing the Brits to minimize this problem), I've never found any of that to be much of a threat. I can imagine that if you're playing more historically and going for poland, france, sealion, then crossing the atlantic for the USA, I can imagine giving them so much more time and involving more powers is definitely going to make it more difficult. But even then, more state AA with AA/radar upgrades and maybe a couple handfuls of fighters (300+ makes AI avoid it?) protecting my important areas might be enough.
I don't think I've ever seen a MP game where the Axis went no-air, and it was pretty heavily derided as a meme strategy outside of the USSR.
I've never gotten far enough along with any particular MP group to be able to play a Major or an Axis major, or influence their meta environment. Yes, the air game is a bit more important and involved in MP, but my talking earlier was centered more around single player which is what OP and most others here I'd imagine are most likely more involved in. I'd also like to think that the very existence of something like no-air soviets being a popular MP approach means that dominating the air isn't really something that you are required to do. I wonder if there have been any multiplayer groups that took that idea in any different directions though.
you talk about paradropping the UK before France is even capitulated, and I find that incredibly memey and not very fun, since the AI can't deal with paratroopers at all.
Yes, the point was to do a semi-historical run so I could get a bunch of the industrial focuses before the war and use a bit of MEFO. Capping the allies early means I didn't have to fight the USA and I didn't have to garrison France so I could focus everything else on the Soviets, beat them up and delete the save. I had fun with it for a while, but I've mostly shifted over to playing as the Soviets now.
