Does anyone use armies? I've played a ton of games and I have yet to use an army created with a great leader. I always save them for Sistine Chapel and J.S. Bach's Cathedral. Once I saved a leader for 5000 years to build Hoover Dam 'cause I only had one city on a river in my entire empire. Are armies that great? I can't see the difference between an army and a good stack of Infantry mixed with tanks. Maybe I'm doing it wrong, but IMHO the best use of leaders is rush building wonders.
