I don't really like it so much.
For me, the micromanagement of sending commanders to scoop up the autogen troops is as bad or worse than clicking a bunch of time.
Reworking troop upkeep is such a big change. I'd rather they just made it easier to select troops. Perhaps a shortcut to recruit 5x of a troop type or something like that?
I agree with you that big armies are fun, though
