Every time I load fixed weps I get jumped by a wing of 3-4 Eagles and can never use them. I have turrets on my larger ships and gimbals on the small - medium ones. They do less damage, but hit more often. A good trade-off for me.
Oh yeah - whatever works for the pilot is what's right
Every time I use gimbals it's chaff, chaff, chaff. Yet when I pack fixed npc's never seem to chaff. How do they know that?
