Destroy or hurt the enemy badly in the beginning of the game so he can't get them. Make sure you have plenty of reconnaissance in the form of towers, flyers (flying machines or zeppelins), and patrols, so you can see them coming. Cast slow on them.
Cast blizzard or death & decay on them when they stop outside your town to bloodlust or when they attack a building. Polymorph them. Put up a cannon tower and surround it with farms and other buildings so the ogre-mages can't touch it.
Cast runes in front of them. Keep a few gryphons or dragons over your town for last-ditch defense. Ogres can't hurt them.
RW: Cast a flame shield on one of them when they are in a group together. Run your units away from them and wait for the bloodlust to wear off. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
