I think as long as we can still see it in something of a graphical manner, as long as behaviour is a little coherent instead of undetectable (like, today, you pretty much can't know which units will be more targeted by archers, or which lines will move first, so many random aspects end making the battle game more a game of strength than strategy)...
I mean, we'll have to know how to estimate which direction archers will choose to fire at, or maybe we choose it ourselves (like line will shoot more to front, while box shoots to all sides, though.... I could go hours discussing this
)
