Turbolasers in Star Wars always reminded me of flak cannons in WWII.
If you're going up against a big Mon Cal cruiser in a TIE Bomber, chances are you won't see the turret that kills you firing at you. It's a 'strength in numbers' kinda thing where even if cap ship gunners are firing off into space they might score a glancing hit on a fighter caught flying too low.
So, I'm all for large banks of turbolasers on capital ships.
Does anyone remember the Star Destroyer vs. Mon Calamari cruiser maps from X-Wing? The neat thing was seeing the big battleships open up on each other with the six or seven batteries and having long strands of red and green cannon fire stretching out across space, mingling in with the clouds of fighters.
