So, it is currently known that turrets will be lock-and-fire and have to be controlled manually by a person for each turret. This beings up a problem. In combat, your average turret gunner will be:
-wait for orders to lock to a target
-lock to target
-rinse and repeat
This will likely be tedious and detract from gameplay. It also won't make much of a difference compared to centrally controlled turrets all aimed by a few people except for adding a weak point of potential miscommunication. So, how do we address the issue?
-A Quasi-Aim System: Make the turrets free-aim but still ude hitscan, with where the person is aiming being a factor in the DPS. While this might make combat more engaging, your average space battle will involve velocities too high for manyal aiming.
-Relegate People to Management Roles: While this may solve the problems of tedium and not being able to hit things, implementing this would reduce the importance of players and something about emergent gameplay and being a social MMO and blah blah blah.....
Of course, no system is perfect.
