Hopefully not. I won't judge until I have something I can play myself, and even then, if this is the way it is in DFM I hope we can change it.
The way ED handles gimbaled weapons is great, no matter what input device you use the reticule is always centred, gimbaled weapons will just adjust aim to hit a target close enough to your reticule rather than allowing free aiming.
Then again, we don't know how ED will handle non-forward facing turrets on larger ships like the Anaconda.
I think having a gunner control a turret like that is fine. It is the way the turret is integrated into the flight control that worries me!
