As soon as I research zers, I produce nothing but zerks - no lancers for cavalry defense, no sentries for infantry defense.
As soon as I research knights I produce nothing but zerks and knights
As soon as I research rams I produce nothing but zerks, knights and rams.
This enables me to take a big city as my first capture and double my points almost over night and only then make that city a defense city while continuing to mass
offensive troops at my main city and choosing next big target.
So, instead of having 1st - defense, 2nd - defense, 3rd - offense it would look like 1st - offense, 2nd - defense, 3rd - offense

I can make large amounts of scouts as well so that no one can scout my city and see what is really going on...
What do you think about that?
