I have been thinking, the AI defense is so bad only shooting if they could heal your survivors, move along the barricades or regroup, the raid would be so hard, the war would be more competitive. A good idea would be the regroup when 3 or more defenders down. All the defenders run into the compound or around the alliance flag. Other thing is the reinforcement when you start to attack 2 or 3 survivor run to this place or advance when suppress.
DON´T FORGET All this how new research with Defense AI note so hard to find and expensive in the shop or in the trade.
What do you opine?
