I don\'t think you are aware of what happens when 2 big objects get close in this game. I was the one that managed to dock his other turret on the ship (wich was way smaller than this turret BTW), and while normally I can run the game fine, getting those two things 30 blocks away from eachother dropped me to 1 FPS and got me a few crashes.
If you want to see an example for yourself, try spawning a ship with 1mil+ blocks and ram a planet with it.
And by the way, the problem is not people using it, but actually managing to dock the damn thing.
