Considering how the 800 m/s is still pretty slow, almost as slow as 600 m/s, I think it should have its DPS raised to around 2800.
I also believe that the 600 m/s should be reverted back to their 1.00 fire rate, making them more difficult to use as they were before but powerful when used correctly.
The 1600 m/s turrets don't seem to turn properly (they might be 2,000, I forget). They were shooting in all completely different directions with only one or two actually shooting in the direction of the fighter behind me.
I was also disappointed to see that the pelican can't mount class 10 fighter missiles on its two front slots anymore; now they're just class 9 fighter gun slots. This is really crap because fighter guns don't fit very well in combination with transport turrets; it would throw focus off. They ought to have the missile mounts like they used to.
Basic Gunboat turrets are ridiculously slow. Why would you nerf them so much? Now they are the same projectile speed as Cerberus... with half the damage per second... Gunboats are supposed to be for defending larger ships against fighters and bombers. Now you're turning them into weaker cruisers where their only viable turrets are miniature Cerberus turrets.
