The problem with ignore Japan strat in this game is that Japan will eat all Asia by round 3-4 as much and start sending troops to Africa round 4-5, stopping the traditional North African dominance strat, and Germany and Italy are stronger than Germany was in Revised so they can hold much more. Not defending Pacific Ocean has also a risk of losing WUSA in 41 scenario (5 starting trannies, probably 2 more built round 1, why do Polar Express when you can catch California instead?). The problem with japs attack on WUSA is that you need one round of preparation to defend from it or Japan will catch you too late to defend, but if you note the menace, Japan will simply shift to Asia without losing none in the process
Anyway, in case of a traditional JTDM approach, lets compare numbers:
- Revised
USSR 25-30
UK 25-30
USA 37-40
Allies 90-100
Germany 30-35
Japan 45-50
Axis 75-85
And still, with a small bid, axis had a 50% chances of win
- Anniversary, 1941 scenario
USSR 20-25 (Arkangel NO lost because of KGF dinamics)
UK 25-30 (if buy SAF IC, if not it will be 20-25)
USA 42-44
China 0 (last chinamen popped China 1)
Allies 90-100
Germany 35-40
Italy 9
Japan 65-70
Axis 110-120
See the pattern? Axis has the economic advantage in this game mid game, not the allies. I really cannot see how allies can win with a ignore Japan strat. If you think Japan is slow now, you are wrong: they have income to purchase tanks and bombers from the rear and fodder from India and Burma or East Indies, and also start with a crazy amount of trannies (arrive to Africa sooner). USA is also slower now because trannies built don’t defend so you must buy more defending boats and italian navy is harder to kill now anyway
A balanced approach will not save your rear normally but at least you have a slim chance because economic gap will be lesser (more NOs to allies; Australia, N.Zealand and Hawaii saved, no trades of Alaska, soviet NO conserved, etc.)
