Maybe we should wait till we have tried DOM II, before telling IW what they should change in it... In worst case, they will do it, and we have to wait a year more before getting the game...

Besides, even though formations would be nice, would they be useful? If they were just a line, a square and a row, this would allow more versatility in battle planning.
But we can already do this even in DOM I, although because commander can only command five different Groups (in DOM1), you would need one commander for every row/line.

And if formations were like shield wall, charge(for knights) etc., they would be hard to implement but would not add much. Yes, they would be useful, but they would either not be much use or would become so important that you would HAVE to quess your opponents' tactic and choose the best formation versus it. And that would add a lot micromanagement.

Of course, you might not agree, but this is only my opinion.
