Actually, I'm building up a Middenheim Army of my own. With the new Warrior Priests and Magic Items, there is at least a change of pace. But, what is an Empire Army without black powder? I don't know if anyone's read "Hammers of Ulric," but this book just like inspired me to have my army join the Cult of Ulric. My suggestion is have both types of armies available; have the original, so you can make use of black powder, and if you feel like you have nothing new to paint, not to mention another fortune in the bank, invest in some of the new characters/units from the Ulric Army. Choose which army you use based on your foe.
