Regards to 2) I disagree, I rarely, if ever, see any American equipment in the Atlantic outside the equipment that America starts with in the Atlantic. This is due, probably, to the fact that Russia can easily out produce Germany and thus stop the incursion without assistance.
Regards to 3) I disagree, Japan cannot earn more than America in three rounds, they cannot do it in 50 rounds either if both sides are evenly matched. If your opponents, or you, are allowing Japan to get 5 of 7 islands, take Hawaii, take NSW, take the DEI, then I suggest you start reading the games here to figure out how to stop them. Stopping Japan from earning more than 40 IPC a round is child’s play - no offense intended. Look about, you’ll see its relatively simple, or PM me for ideas on how to stop Japan, you are probably just overlooking convenient ways to abuse airbases and naval bases.
Regards to 4) America does not need to buy battleships to counter Japanese ones. Battleships are HIGHLY inefficient. However, America does need cheap destroyers and submarines (as does Japan.) Now the difference is, America can buy 2 submarines for every 1 submarine Japan buys, 2 destroyers for every 1 Japan buys. Add in Australia/England warships and you quickly dwarf the Japanese fleet.
Regards to 5) I would love to GET the DEI for a change! But I think you are missing how easy it is to sack Tokyo now. If you have your fleet down there, Hawaiian ships can destroy you, if you have your fleet up there, Australian fleets (Americans off Australia) will quickly take DEI back. Getting DEI is pretty impossible now due to how fast America can move and get ships to bear.
Perhaps we just need to remove the Naval Bases from Hawaii, Carolines, Queensland, New South Wales, India, Malaya and Kwangtung? (Hong Kong). They could be rebuilt, but it would effectively make it possible to get DEI with England without being murdered for it.
Now, granted, if you play with USA going in the Atlantic, then you are effectively splitting America’s income, are you not? You put enough in the Pacific to maintain the Hawaiian, Alaskan, Mexican and Continental NOs and the rest in the Atlantic? If more people played that way, there would be no issue! The issue comes with the Russian Turtle + Crucify Japan strategy that is the common proceedure. Why is it common? Because it’s 90% effective (or more) and there is nothing the Axis can do about it unless they get REALLY lucky with the dice.
