Right! The really really big ones. I though they were the turbos and the smaller ones werd just turrets of some sort. My bad!

No worries, the normal turbo laser turrets are relatively small compared to the Quads and especially to the size of an ISD.

Right, but the shielding is the key word. I wasn’t saying it was weak in that it couldn’t have an inventive use. I meant weak in that it had less offensive capabilities for a line fight like at the start of III. I mean, you could eventually cut someone in half with individual sheets of paper doing paper cuts over and over. But using a saw would be more practical.

That’s true, though in that case you move away. Unless both ships have the exact same speed and heading, they’d diverge relatively quickly. Line fighting usually involves constant movement. So unloading a broadside or two probably doesn’t do that much.

Oh, and I just had a quick look at the fight. So apparently the Venators have a big death laser around the lower hangar section. At minute 2:50 it is used to blast a Munificent apart. It might very well be, that it is the same type of weapon used by the Empire for Planetary Bombardments, or purpose built for the Clone Wars.
