Rectangular Formations

[sector24]

In the Total War games, you can set the depth of your formation, so you can have a wide block of men 3 deep or a more square-like formation 7 deep. The consequences in that game is that if the enemy breaks through your line and splits you in two, it's a huge morale penalty.

I think that would be a good addition in some form to Dominions, but probably not in Dom3.
