Generals
Some of the nice new improvements I have seen include the ability to choose the general you appoint when you 'create' a new one.
Generals can also get wounded in battle as well as killed (and have to heal for several weeks after the fight).
I didn't like that the enemy artillery really seemed to focus on my general unit rather than any of my troops.. but maybe that was just a coincidence.
"A Foot Soldier is commonly a Man, who for the sake of wearing a Sword, and the Honour of being term'd a Gentleman, is coax'd from a Handicraft Trade, whereby he might Live comfortably, to bear Arms for his King and Country, whereby he has the hopes of nothing but to Live Starvingly...The best end he can expect to make, is to Die in the Bed of Honour; and the greatest Living Marks of his Bravery, to recommend him at once to the World's Praise and Pity, are Crippled Limbs, with which I shall leave him to beg a better Lively Hood."
