Whilst discussing "realistic' and "practical" does seem a little farcical in a 31st Century game that ONLY has WVR Weapons and typical engagement ranges of 500M - 1Km (Yes!!! In Space!!!)
Wouldn't Fixed weapons make even MORE sense in space (off axis movement and shots FAR more viable than in atmospheric flight)
No, I don't think fixed weapons have any advantages in space. And the energy needed to turn a turret is much less than that needed to turn a whole spaceship.
This needn't be an argument. I know that many people like the fighter-ace-in-space thing and I hope they continue to enjoy it. It just happens that I don't. However, I find I can improve my enjoyment of ED by making it conform a little more to what I regard as realism. When I equip a ship with what I think are more likely ways to fight a battle in space, the game becomes more interesting to me. So that's what I do. Blaze your own trail.
I take your point about ED being unrealistic anyway (Gatling guns in space! It's more steampunk really), but in order to play I have to suspend disbelief. A bit of RP, choice of game activities and attention to "space-ish" ship build does this for me.
