Oh man I know! I had a fleet of destroyers with two battleships, and their mission was to knock out enemy roads and city defences. How surprised was I when my high tech killing machines were missing pikemen. What was even worse was when my badd-ass battleships rolled up and "failed" to wipe out improvements. C'mon, I thought the artillery and catapult was bad.
I HATE BOMBARDMENT - was theoretically a great idea.
