Some pirates prefer attacking ressources, some prefer destroying defenses. To add more strategies, we could have group or solo behavior: - Pirates with "group" behavior will tend to choose the same building to attack next, even if they were dispersed by a mortar. No more solo guy loosing time alone on a building, but more meat for the mortar... - Pirates with "solo" behavior will tend to spread to attack different buildings. No more feast for the mortar, but more chances to see pirates trying to defeat some target alone...
