Having your ship turn slower when stopped would certainly fit in with whats been seen in X-Wing and to a lesser extent SWGalaxies. It would probably balance out the gameplay better if that was the case anyway. I wonder if the devs could somehow work in the maneuverability/speed aspect of the x-wing games
ie. ships at 2/3 throttle and 1/3 throttle handle better than ships at full throttle, whilst obviously being at greater risk from the fact they are a slower moving target.
It might produce some interesting dogfights as people develop their prefered tactics. I'm not sure how hard it would be to implement though
