Difficulty too easy, units ignore being attacked

[Zombie-Ryushu]

The game's difficulty gets too easy, because enemy units ignore the town being attacked. They will not retaliate unless the units are attacked, engaged, or in range directly. Additionally, Computer opponents in campaign maps will not train advanced units because they have not progressed up the tech tree naturally. They will also not attempt to expand the territory they control, they will only build extra town halls nearer to mines.

There may be a place for additional difficulty toggles.

The AI has become more passive, and is no longer displaying the aggression it used too.
