Allies ground army comps to suit mass air
I like to play mass air with the Allies doctrine, but am not too sure about which ground units to use with it. Playing mass air means that I inevitably have a smaller ground army, so huge rocket artillery stacks don't work that well. The traditional, heavily mechanised build with mech inf, TD and SP arty is simply too oil-heavy, and it seems unnecessary to have both SP arty AND TD countering heavy armour. Only one is needed.
After a bit of looking at stats and resources, I have figured that one big rocket artillery stack and a few stacks of 10 mech. inf + 5TD, with plenty of ACs as scouts/runners is the best option.
But there is one problem that I have never understood: What do I do with my starting units? I can't just throw them away in early expansion, so I chose to put it into one rocket artillery stack with the other 5 infantry just doing nothing or taking care of runners in my core provinces. The rocket artillery stack doesn't usually see much action, so I often contemplate not forming one. But then, where do my starting inf go? It's like a paradox (that I've overcomplicated myself)
One thing is for sure: I'm overthinking this. Yet my attitude toward this game forces me to make actual stacks because I dont trust a small stack of inf going around with inadequate AA/AT.
Wtf should I do?
