There's a pretty clear overarching problem here in the way the campaign strategy works. Entrenching positions and building up strong defensive forces is pretty meaningless when sending a single of the cheapest unit in the game is such a devastating manoeuvre. The auto-resolve is trying to match how the rts potion works but they're both broken. Sending a constant stream of cheap units into battle is a completely degenerate strategy and there seems to be no counter to it.
