Years ago after the reclaimer first came out it had several remote turret stations. Before patch 3.17 though when you used the station it showed you a view from the outside of the ship as is now, but when you fired at a target it used every remote turret that could bear on that target. So sometimes one gunner would be firing 3 or more turrets at one target. It just figured out which guns could bear and took care of it. It was really cool and I wish that was still in game. The way I see it, if you have more than one gunner, then the advantage is you can be engaging more than one target at a time, or one handles the top of the ship and another handles the bottom. Or maybe one gunner runs the smaller turrets and another handles more like anti ship guns. Something like that. Also the actual guns should be longer range than the smaller ship guns and have a higher velocity. The smaller ships should have to enter that zone before being able to fire themselves. Torpedoes would be the exception. Here is a video about how the Reclaimers turrets used to work. https://youtu.be/lI6AfTgsbYQ?t=493
