from my experience it seems to work best if Japan forgoes the Phil and maybe even Yunnan, positions Everything (except BB) that can land on India T2 to do so.
Germany has to make some attack on EGY (I can’t say if it is better to do so with or without the bomber) and sink all but the Canadian DD. landing all surviving Air units on N Africa, France, and Sweden. Depending on what survives between Air and Navy the UK can be in a bit of a UK1 bind. After that it is critical to beeline and stack East Poland, everyother front being secondary.
Japan tries to beeline to India (prime objective), make a path through China (objective 2; it can leave a couple out of the way remote territories such as Yunnan and Hong Kong alone), filter a navy to the Med, tries to build an air pipeline to Europe/Persia, than whateves (most likely the Pacific or Africa).
Italy builds all ground tring to get a small tank stack to double hit russia concentrated in E. Poland as quick as possible or secure the Ukraine. It only really worries about having Egy secured in Africa and opening up the suez canal for Japanese ships. The main function though would be to protect France
A funny thing to watch out for is to see if a G2 or 3 all bomber build is tenable to kill russia the following turn. It is something a blitzing player needs to keep in the back of his mind. And has to know when to position his air power to hit Moscow.
This is the best way I see an all tank German build working, overall a kind of “beeline strat”, I think it is HEAVILY dependant on your G1 breaks in EGY and Naval attacks and how much you lost while taking the Balkans.
