another ai problem i saw it's that they keep building close to your base(literally net to your capitol)this makes them build the most epensive buildings and make's them loso so easilly or destroy you in seconds(i noticed that that necromancers sometimes wont attack the buildings).i think this could be solved if you could only build in your own terrain i liked how the undead have that raise dead from the altar of darkness,really good defense!
really good mod,just hope more people will start playing more hoae when the later versions come,really good game
