Ahem... yes, I agree about the rule suggestion for the Army book.
Another thing that would surely spice up tourneys would be if the players where forced to "dress up" for the occasion, preferably in the proper race, but at least in some proper warhammeresque outfit!
Man, it might be hard for me to be an asrai, but I would have some awesome suit.
And yes, extra points for the general that has the "best outfit", especially if he made sure his base is themed along the lines of his army.
