I would like to see more conventional WW2 Theatres where the strengt of your engine (mechanized warfare on Battalion level) gets to work.
And the most interesting battles with this are between germany and russia on the east front not deep in the forest somewere on the russian-japanese border or Karelija.
So on Nomongan exactly what it was - a huge "crowd" of armors at the tank accessible areas (no forests at all

). Better and bigger than in most Easter front battles.
For Steel Armor i would like to see something like Fulda 1985 (hypotetical battle between nato and the east in germany).
It's hard and expensive to work at landscapes at first.
