How about a direct control mode for individual units ingame.
What this mode would allow you to do is to control a vehicle with the keyboard and direct targets to the turret with the mouse.
Sort of like in Soldiers Heroes of World War 2/Dogs of War/Faces of War/Joint Strike Force.
I think its about time they had a feature like this in every RTS game.
It would the game more interesting, sometimes clicking all the time to tell units where to go gets really boring.
