Fortress versus Necropolis.

Logistics are always needed on large maps: if you have artificial logistics + travel time! And of course - a sharp Mind! If you place Subjugation before other skills, it will be a devastating blow! + your turns will be 1.5 times longer than your opponent's, and this is very important on large maps!

Regarding Berserkers - if someone doesn't know, they have immunity to mind control spells.

I mixed it up! Place Berserk on the Priests, and Subjugation on a strong stack of Jarls! Means: Machines, Magic, Darkness, Education, Attack.
