The real issue, in my mind, is that 10 IPC NO for America in America where it cannot be sniped, it cannot even draw American forces away to go reclaim it like the Aleutians, Line Islands or New Britian for ANZAC. Without that NO the Japan vs America game becomes more balanced. At least, it’s 2 destroyers America is not building! (1 destoryer 8 IPC and you are still short 2 more IPC that you need for the second destroyer!)
Eh, for Delta, when we get to NOs, I’ll recommend splitting the American economy. You spend in the Atlantic what you got in the Atlantic and what you get in the Pacific in the Pacific. Then boost the NO from 10 to 15 with 10 Pacific and 5 Atlantic (Link the Atlantic one to W. Indies and Pacific one to Wake and Midway so they can both be sniped). The stuff from the Atlantic can still get to the Pacific, it just takes an extra round to get them into position - or two rounds if you are winning in the Pacific. To compensate, I’m giving you 5 more IPC a round, dude, what more could you ask for!
