I've had 2 common complaints which were sort of clashing:
1. When your ship gets too big, turning is too slow - making it difficult to fight
2. Having a big ship that turns too fast seems unrealistic, basically all ships are variously sized fighter ships
I've decided I'll keep the slow turning when your ship gets larger and add some new weapons which work better for large ships.
Introducing Aimable Weapons! You can now get modules which fire toward your cursor rather than straight ahead. This means you can shoot in any direction and dont have to worry about pesky small ships running circles around you. This combined with the A&D turning (instead of mouse turning) will make large ships much more viable despite being slow turners.
