I am SO sick of having my Infantry's getting their butts kicked by horsemen and Impi's. Or when I attack a Knight with my Calvary, they get beat 50% of the time. Or on the water, ironclads killing my battleships. I understand luck and all, but REALLY! I spend a lot of money on upgrading my units. The AI doesn't. Yet, they go toe to toe with me and do great. Doesn't make sense. I think they should add something where with each age, all the units in that age get a slight advantage over the one before it, progressively getting more serious as they get further apart. Like an Industrial age unit fighting an Ancient one.
