Quote from Lynsey: Thieves like gold and grog, and will seek distilleries, gold mines and storages. They won't attack anything else unless all of the former have been thoroughly plundered. Brutes prefer to attack defences, but will attack other buildings if there aren't any defences nearby. Juggernauts like to detonate mines that are within a certain distance, and will leap over walls to get to them. Bombers like to attack things that are surrounded by walls if they're within a certain distance. Sky Raiders with the Death from Above ability will attack the tallest buildings that they fly past. Very large or tall structures will cause them to fall to the ground. Priestesses will prioritise destroying defences within a certain distance Witch Doctors try not to step on each other's toes, so if some damage dealers split away from the main pack and there are two witch doctors deployed, one of them will probably decide that they should go with the outcasts. Everyone else will attack whatever's nearest.
