I think it woulb be good if the turrets would respond according to a players activity, and go off after a period of inactivity. I would suggest anything between 15 to 30 days top for full turret inactivity. Active player would benefit and inactive wouldn't.
Something needs to be done with turrets since new update. Those of us who enjoy expanding hive and clearing the uncountable amount of inactives have been screwed. Above suggestion is a start, also why are the turrets not damaged to make deactivated till repaired?
